Hello Andrei,
Regarding your original post:
It sounds like you had a beautiful experience, a holy experience. I use the word "holy" here in a very practical sense: out of the ordinary, felt as very meaningful and possibly life changing. I avoid the word "samadhi" because I understood it has different meanings in different schools.
In your original post you say:
"If
you watch long enough . . . " and "
you will experience . . . "
It sounds like you want to teach how to meditate. Am I right in that?
If so, the fact that you had a holy experience speaks for you as a teacher.
I suppose that there are a lot of people who teach meditation, or yoga, or mindfulness, and who never had an experience like yours. I do not know - I do not have an exchange with meditation teachers.

But, sorry, it takes a lot more to be a teacher.
Let us go back to this text:
"If you watch long enough . . . " and "you will experience . . . "
How do you know this will work for an other person? And, would indeed the experience be so impressive for an other person?
You seem to think that teaching is to make copies of your own person / experience. It is not.
Teaching starts with seeing where some else is, and what they need. And it is their right to tell what they need.
(I know - I taught at a holiday sailing school long ago.)
I am sure Samadhi is the same for everybody! This is where we all meet:-)
That is a conviction, and in my opinion it is part of the character of such a holy experience. It is felt as the place "where we all will meet". And it is felt as universal. The power of such an experience can give the individual a sense of entitlement - like: "I know what is good for you!".
That conviction, that sometimes follows after a holy experience, can make someone lonely. And that sense of entitlement, if it is there, can make someone very lonely. (I saw this with my father.)
So . . . You said that you hope to hear from people with the same experience.
The funny thing is: You did. To the best of my knowledge, you did here from people with comparable experience.
Maybe you should simply consider how that can be possible.
