这些声音,我们在职场中常常听到,其实有些也来自自己的内心
“凭什么他一个刚来的新员工,工资竟然比我这个入职5年的都高?”
“这个项目明明是我完成的,凭什么功劳都是他的了?”
“明明是我在天天加班加点,凭什么升职的却是她?”
醒醒吧,小伙伴,从你踏入职场的第一天起,就不该期待公平,更何况,你所谓的公平
,只是来自于你内心的看法罢了。
世界上本来就没有那么多“你应该”和“本来就”,职场上弱肉强食,优胜劣汰的故事
看的太多,踩着被人上位,一将功成万骨枯的故事天天在上演。
一个刚来一个月的新员工,说不定是你的老板高薪从猎头手里挖过来的人才;
这个项目明明是你完成的,但是人家会领导啊,会做报告啊,会做PPT啊,哄得老板心
花怒放,功劳不算人家的算谁的?
明明是你在加班加点,但人家下班的时间也没闲着,读书进修考证,英语说的比老外都
溜,以后接待大客户,难道就靠你的加班审批表吗?
从小到大,我看到最公平的事情,大概就是高考了,就连高考,也有不公平啊,为什么
北京的孩子可以轻易考上重点大学,山东的孩子600多分还上不了211?
世间的公平是相对的,不是绝对的,打铁还需自身硬,与其纠结抱怨为什么不公平,还
是先自己修炼修炼吧!

I want to start a new post on this question, also as a response to Yisu's
post earlier.
I also feel that the will to understand the Truth is very important, and it
is closely related to the faith.
Well, what is the will to find the Truth? What is it exactly? Is it the
belief that there must be a reason, aka, karma? Is it the faith that there
must be a way out, aka, nirvana? Or is it the intuition (built-in essence of
a soul, or collective unconscious, or whatever it's called) that keeps
calling on us to pursue it?
Do you think that there is only ONE, or only nirvana is the ultimate ONE? I
want an answer not by Buddhism Sutra, but by what you feel in heart, or what
you understand as of now, in your current status.
I am asking this also because I was reading that book "Conversations with
God, book 2" over the Thanksgiving break, and I watched the DVD, which might
be based on book 1 that I haven't read yet. In the DVD, Neale had
encountered a very bad car accident, lost his job, lived in a tent in a park
as being practically homeless for a long time, before he found himself a
new job, and yet this radio station (he was a DJ there) went bankrupt
without anyone telling him anything beforehand. That's when he asked God why
why why till he found the answers in his head that he just needed to write
it down on a notepad.
The key thing I want to understand more is the concept of time, and this
book explains it as being a spindle with leaves of pages, as if each page is
a time instant, and they are always there, and we can peek into the past or
the future, or essentially there's no time, or, there is only present
moment.
Then regarding where God is, this book answers it as everywhere, as What It
Is. Since it's everywhere, it's also nowhere, as any place of itself would
be a separation from other places, but it's not, it's everywhere. Also, as
mentioned by freeman08, nowhere= Now Here.

Sorry, I missed this post..Let me take a look..the question is why do you
think that Buddha can become Budda?
En...I think firstly it because he, like anyone else, has the potential to
become a Budda. It's like a seed planted, and with certain condition, it
surely will flourish one day. According to the Budda, everyone has the seed,
and everyone will eventually be there. But speaking of the last one, why is
him, not Y is U, or not Y is me..
I think the most imporant difference between he and us is the WILL.
And also how strong the will is to know the truth, to practice, and to get
there.
The inital will is so strong that it supports practise over the countless
lifes and the practice on the way reversely make the will stronger, making
it a healhty progressing.
Those who think he has not been improved over years should check the will
first, is that strong enough. Like the exmaple I mentioned in another post,
sth like a person's will to get above the water.
I believed he has undergone much much more practices and tests than us in
all his lifes. looks like that's the reason, but that could be a result at
the same time too..

呵呵,你好像问不只一个问题
will, belief, intuition,
GOD(s), truth, faith, time...
估计没有一个是有标准答案的
就个人感觉友情灌点水。
“Well, what is the will to find the Truth? What is it exactly? Is it the
belief that there must be a reason, aka, karma? Is it the faith that there
must be a way out, aka, nirvana? Or is it the intuition (built-in essence of
a soul, or collective unconscious, or whatever it's called) that keeps

不太清楚,但是圣经里的一句话,
比较符合我的感觉
...and the truth will set you free." (John 8:32)
“Do you think that there is only ONE, or only nirvana is the ultimate ONE?
I
want an answer not by Buddhism Sutra, but by what you feel in heart, or what
you understand as of now, in your current status.”
就我个人而言,GOD就一个
那就是自然界的规律。
但反映到人的意识时
会有不同的认识。
“The key thing I want to understand more is the concept of time, and this
book explains it as being a spindle with leaves of pages, as if each page is
a time instant, and they are always there, and we can peek into the past or
the future, or essentially there's no time, or, there is only present

我对时间认识来自钟和相对论
但是我还是不懂的时间到底是什麽。呵呵
“Then regarding where God is, this book answers it as everywhere, as What
It
Is. Since it's everywhere, it's also nowhere, as any place of itself would
be a separation from other places, but it's not, it's everywhere. Also, as

自然规律无处不在。
所以GOD也是无处不在。

哈,为了能表达清楚一些,我还是用中文吧,
这么多问题,也不知道该从哪里开始说,就说到哪里是哪里吧。。反正都是个人看法.
佛是悟了的众生,而众生是未悟得佛。 可是佛为什么能悟呢,却也不是和众生豪无关
系,佛的力量来自众生。 为什么这么说呢?
还是举了例子吧。 一杯水,你拿起来摇一摇,有一滴水掉了出来。 我们来仔细考察一
下这一滴掉出来的水珠。 是什么让他掉了出来,而不是别的水珠? 摇动是一个因,还
有什么呢?
是否可以说,没有别的水珠,在相同的摇动下,它也可以出来呢? 显然,其它的水珠
的存在是这个水珠出来的另一原因(反作用力)。唯一不同的是水珠没有人一样的意识。
佛的觉悟过程也是类似的,在因缘条件满足下,肯定有一个人要成佛,但这是统一作用
的结果,即是个人的愿望和实践,又是众生的愿望和实践。
佛在忍辱仙人的时候,被人肢解,反对那个人说,以后我成佛,先来度你。 什么意思
? 因为正是这个人帮了他大忙。 佛法在世间,不离世间觉。 世间无常是苦,觉者反
转为菩提。 佛以众生心为心,众生有多苦,佛就有多少慈悲。 所以我们问佛的力量和
智慧从哪里来,我觉得就是众生。
那么这个世界的本质是不是一个。 与神对话是一本很有意思的书。我认同其中很多道
理。比如说第一本中提到的神圣二分法。 这一点在中国传统宗教中,尤其是道教,反
映的比较多。道教是隐晦隐晦地讲,而这本书就是明明白白地说。
是,这本书的确很多地方提到了唯一的存在。我个人觉得可能是语言文字的效果, 那
可能并不是他想要表达的。 襌宗有以个公案讲的是有益个和尚问赵州:万法归一,一
归何所?赵州曰:“老僧在青州,作得一领布衫,重七斤。。。
这个公案是在打破这个和尚对一的执着。 每一个执着, 不管是对一也好,对万也好
,都是应该放下的。 一又在哪里呢? 一不就是万法吗。。道家讲道生一,一生。。。
, 一从道来, 但是道却非一非二。 道非一二,却以一二的形式来展现。
所以我不认为有这么“一个”,因为我希望能真正见到这么“一个”。

Interesting discussion and I want to give you my thoughts.
The "ONE" or nirvana, or whatever you want to call it, is within you. It is
your true nature. So what it our true nature? We all want to be happy, we
all love our our parents, we all want to be worry free, we all want to do
things effortlessly and fearlessly, etc., this is our true nature - the
state of happiness, love and kindness, fearless and no worry. This state is
born with us, it is our true nature. Nothing can change this state, and this
state does not depend on any outside support. This is the truth. When we
don't recognize our true nature, this is called "无明". Buddhism is a path
to discover our true nature and be with our true nature so that we don't
have suffering.

en. It makes sense.
I tend to believe that it does not matter which way one chooses to be
connected with this ONE/Wisdom/God (whatever it's called), and religions are
especially limiting with rituals and bans. There's some discussion in this
book on how Christianity is ridiculously practiced, and it seems the same to
me in other religions. However, a good teacher is also very helpful on this
journey. Both are needed.

Thank you very much! I really appreciate it.
I also believe that every soul has that born and true nature, and every soul
is truly equal in this journey.
In Buddhism, there are different levels of awareness. That's something that
I am still pondering upon. How would one evaluate that? Although I hear that
measuring itself is also an obstacle to reaching either level. I want to
understand this evaluation more, as I want to know how would one know other
approaches, other than Buddhism, do not reach the same One? Could you share
more thoughts on this?

You are welcome. Good discussion is nice to have.
I am not sure what you mean by "levels of awareness". Can you explain?
If we give awareness a definition, I would say awareness is the ability to
see the movement in the mind. Or one can say awareness is the clearity of
the mind. It's the same meaning. The awareness is born with us and it can
cut though anything appears in the mind. As a begginer meditator, the
awareness is hidden behind the thoughts and emotions and can not be seen. As
one progresses in medition, the mind become calmer and the awareness become
clearer. As the meditator continues to progress, the awareness become so
clear, that it is realizes as the natural born wisdom. The awareness is the
same awareness, but the experience changes as the meditation progress.
As for your question regarding how could one know other approaches, other
than Buddhism, do not reach the same One, I can not say other approaches can
not reach the same level as Buddha. But I can say for sure that no other
approaches can surpass the level of Buddha. The awareness, this natural born
wisdom, is so sharp and it can cut through anything and any suffering, what
else can surpass it?

Thank you so much!
By different levels of awareness, I meant different levels or kinds of 解脱,
and the different levels of souls such as 佛、菩薩、天、人、阿修羅, etc. It
somehow seems to me that it's either a yes to be in that awareness or a no,
at each instant, but not something like 50% there, 90% there, etc. However,
I do have a level in mind, as how evolved a soul can be, in the sense how
often the soul can maintain that awareness. Once a soul reaches some
awareness, the soul may not stay in that awareness though. May I know what
you want to say more about this?
I liked your explanation on the awareness. I don't think that there's any
way that surpasses another, but rather all lead to the same One (or
awareness, or wisdom, etc). As I mentioned on this board earlier, Eckhart
Tolle, or Byron Katie, or many others had some profound spiritual
experiences, how do you evaluate their experiences by Buddhism standard, and
how confident are you in such evaluation?

True Nature 就是心的本性。心性广大如虚空,但心性不仅是如虚空,不是绝对的空
无所有。超越一切相对的明空与慈悲喜舍其实是不可分割的。我们凡夫的乐往往是有得
失,有对境的乐。而我们与生俱来的心性中的乐与慈是无得失,无对境的广大的乐和慈

看的角度不同。

Awareness has three special properties: emptiness, clearity and ability to
know. Ability to know I mean it can know what your are thinking or what you
are doing. We are living beings because we all have this natural ability to
know. Empty means it has no shape or color or meaning, and it is not a
subject or object. You can't even describe it. The moment you describe it,
it becomes an object and it not true anymore. Normally because of strong
grasping by the mind, our awareness is covered by the thoughts and emotions.
But awareness is always there.
Words are pretty much reach its limit here. 你可以去看看禅宗祖师的开示.

I was busy at work this morning and did not have time to type an example.
Now I have a little bit of time and I will try to explain to you with an
example. Suppose you are in a room. When you do not see anybody else in the
room, you know you are the only one in the room. This same situation can be
applied to awareness. Suppose this room has light - awareness is like the
light. Let's say there is nothing in the room except light. The room is
totally empty. Remember the awareness has the ability to know. Normally the
awareness is always busy knowing all the things happening in the room. Now
the room is totally empty. The awareness still try to know what's happening
in the room - try to know. What awareness sees? Only emptiness and clarity (
light), right? What is emptiness and light (clarity)? - Awareness. The
awareness is trying to know what's going on the room, instead it only see
the emptiness and clarity - which is itself. Now let's replace the room with
mind. Mind is just like a busy room, normally have lots of stuff going. But
when the mind is empty, what awareness sees? - Only emptiness and clarity.
This is one way awareness can see itself. That's why 早期襌宗提唱“无念为宗
”。
Without knowing your background on the path of Buddhism, I hope this is not
too strange or too difficult to you. But this is in deed difficult to
understand and also difficult to explain. The awareness has the ability to
know itself. This one of properties of awareness. This is the key point.

How to let the room of mind be empty?
How could the mind be empty?
When the mind is empty, could the awareness still work?
What is the physiological basis of our busy mind and the awareness?
Do they need similar mechanisms to run?

How to perform “无念”?
How to judge the awareness is the true awareness?
Could you give a scientific definition or description of the awareness?

You are welcome. I am not sure I can answer your questions, but I will try.
From your questions, I just realized that our discussion is a little too
advanced for you (don't get offended,:)), so i am going to back down to some
basics. I don't come to this board often and I don't know everyone's
background in Buddhism study. So, first, I want to ask you: do you do
meditation? A lot of things I am talking about above are based on meditation
experience. Without meditation, it is difficult to progress in the Buddhism
study. Second question, what kind of Buddhism text or books have you
studied?

First I should say thanks a lot for your detailed reply. :-)
Why does the awareness have the ability to know the room of mind is empty?
How to let the room of mind be empty?
>> Do you mean room or mind? Maybe you did not fully understand the example.
Maybe my example is not good example. :)
How could the mind be empty?
>>For begginers, it is difficult to detect. As you advance in meditation,
just let go of the thoughts, you can experience empty mind.
When the mind is empty, could the awareness still work?
>>Yes.
What is the physiological basis of our busy mind and the awareness?
>>Not sure what you mean. Just look at yourself, is your mind always
thinking about something?
Do they need similar mechanisms to run?
>>Again, not sure what you mean. Do you mean are they the function of the
brain cell? To me, I don't care. I just know from meditation experience and
buddhism study how mind and awareness work.
“无念”?
>>When mind is not thinking anything - no thought.
How to perform “无念”?
>> This is impossible for begginers. 念是心的功能,故无需刻意去造作无念.
How to judge the awareness is the true awareness?
>>For begginers, it is impossible to judge. It is also not neccessary. When
meditation, just be mindful of the meditation object.
Could you give a scientific definition or description of the awareness?
>>No, I don't have scientific definition of the awareness.
Waiting for more input from you. Thanks!

Could I ask some similar questions to you? How many years did you practice

is very nice to hear that you may practice meditation for quite long time.
However, what I can not understand in the discussion there are always such a
lot judgements unrelated to the question itself. All the great teachers I
met never answered my questions in this way.Convincing answers come from
decent logic, clear definitions, the peacefulness and confidence sensed by
the audience.
I was not offended. ha
I asked those questions which may seem quite simple, but actually not so
easy to answer. I asked them because I had some answers or my own opinions
in my mind.
The Buddhism I am learning is quite different with what you prefer. But I
still want to know how you think about those questions.
thanks anyway!
I have sth to do, and may discuss with you in details some days later.

目前的观点是,HR和NHEJ是在DNA双链断裂修复中互相竞争的pathways。如果能够有效
的抑制NHEJ,HR的频率有可能会有大幅度的提升。目前,一些labs主要通过knock out或
者knock down NHEJ中几个关键player, 比如,Ku70, Ku80 以及Ligase4,来进行验
证。比较convincing的data有Dana Carroll在果蝇的研究,以及Eric Hendrickson在
mammalian cell line中的研究。Paper 如下:
Proc Natl Acad Sci U S A. 2008 Jun 24;105(25):8703-8. Epub 2008 Jun 18.
Ku70, an essential gene, modulates the frequency of rAAV-mediated gene
targeting in human somatic cells.

Genetic analysis of zinc-finger nuclease-induced gene targeting in
Drosophila.
Bozas A, Beumer KJ, Trautman JK, Carroll D.
不过,细胞究竟会使用什么pathway修复双链断裂应该复杂得多。至少细胞周期和发育
阶段也会对pathway的选择有很大影响。我曾经和一个做fish的PI聊过为什么ZFN-
mediated HR在fish里的效果这么不理想。他的看法是fish的embryo发育太快,所以一
旦有双链断裂需要修复,细胞会采取最快捷的NHEJ来修复,而不是需要更多时间和能量
的HR.

下一步就是要拿到germline
光是chimera 还发不了大paper.
其实HR肯定可以发生,就是效率太低。
俺有一个想法就是
如果直接manipulate embryos效率太低的话,可以先转一个artificial chromosome作
一个stableline.然后跟抑制NHJR的mutant line cross,然后后代筛选homologous
recombinants.
鱼能产很多卵,筛选几万个应该不难。

我最近在研究全老鼠的imaging...
技术上最近还是颇有些新方法的, 我觉得以后看个胚胎应该是可以的。

最近很有几篇TALEN的应用 看起来效率至少不比ZFN差啊 programability更是远胜
