I had a no-self experience, why is it a good state? I've been meditating for about 4 months without (seemingly) getting somewhere up till about 2 weeks ago when something clicked for me after watching some interviews and talks from Gary Weber and thinking carefully about what was preventing me from really meditating. 

I became pretty obsessed with really seeing things clearly with the over two consecutive weekends with the "goal" of reaching the first samatha jhana (of which I already had a previous encounter). 

In the first weekend I really tried to calm down the whole day and medidate the most I could take. Reaching high concentration was easier that day but still not sufficient for full blown jhana.

In the second weekend I began working on it more and reaching something like 60% there. The next day I tried to reach it again and failed because of the attachment to reach there. After learning about the practice that Gary Weber and Ramana Maharshi reccomend (who is thinking? Who is hearing? Etc..) I tried it and immidietly found it extremely potent, much more potent than regular vipassana. I soaked myself in this kind of meditation all remaining day until I got to sleep. 

After I fell asleep I had a visualization of me seeing thoughts come in and physically putting them on the shelf, one by one. Also focusing on the feeling of 'I' there. 

After about an hour of sleep, I suddenly found myself in the middle of switching pillows bu my whole perception completely changed. I noticed the following things:


The sense of an 'I' was gone. I continued to search for it but it was no longer there.
Experience seemed to flow one moment after another by itself without any intervention or will. Each moment kind of forces the next to nesserally, logically happen.
There was a sense of complete detachment, no will to be in this state nor to not be in it. There was just an analytic curiosity about what happens in the moment. I knew at that moment that there could not be any suffering.


So I guess I had a glipse of how it is to be awakened. And what is called "the arising and passing away" or "dependent origination". But that's just empty language. 

Since then I find it much easier to slip into mindfulness, sense an attachment, automatically see the suffering in it and let it go. 

When mindfulness is present the world seems to be completely neutral and analytic. There's no suffering but no joy either. I can see the benefit of removing suffering, but I dont see the joy of this analytic neutral state. I think there's something I'm missing or failing to notice. 

What is the joy or bliss that supposedly arises by being mindful and present?
When I told my Zen Roshi that "I didn't exist," he simply tapped my leg and said, "What's that?" I was completely baffled and tongue-tied.

If the "world seems to be completely neutral and analytic", this can be due to indifference (i.e., lay equanimity) or renunuciate equanimity. The difference is subtle and warrants further practice and study.


  Therein, by relying on the six kinds of renunciate equanimity, give up the six kinds of lay equanimity. --MN137


Regarding your question about joy or bliss, you might be interested to read about the eight liberations. In particular, the third liberation involves beauty. Indifference cannot see beauty.


  They’re focused only on beauty. This is the third liberation. --AN8.66


The challenge provided by being just neutral and analytic is that one is still beset by choices, and those choices become more and more difficult with greater insight. Here, precepts become increasingly important along with further practice. 

Also study the brahmaviharas.
