That was a very interesting video.
In some ways I have discussed something similar with friends that I thought about mentioning here a few times, so here is a good opportunity (warning this may be a long story).
It started after my youngest daughter (probably 4 or 5 at the time) asked where she was when we were talking about time before she was born.
At first I would answer that she wasn’t here, may be not saying that she didn’t exist (that sounds really harsh but in French it has a milder tone) but that was clearly on the back of my mind.
Anyhow, time went by, and I continued along my path, and at some point she asked the question again.
But then my answer had changed. Dramatically.
The answer she got was that she was here, already, but in a different form.
When she further inquired on what or where she was, I explained that what made her in her mother belly, and what makes her now, are natural elements that fed her life and allowed her to grow, so may be she was in manu palnts, minerals, other abimals, air or water all at the same time.
Then I continued stating that, in all honnestly, the one and only one thing her mother and I gave her, is the “spark” or “magic” that we all have in common: life, which we also had gotten from our parent that received it from their parent etc etc.
Now this is what I would kind of recognise from the video when it says that " you are everyone, past present and future" (I may be re- or mis-interpreting here)
Now, back to my friends: we were discussing similar matters and I discussed the story from Lucie’s question.
And at the end my friend asked me: if you are not your body, don’t you feel dis-embodied?
To which I answered that when you are not associating with your body or anything else in particular, you just feel life.
And you see other life around you, which is simply beautiful in all shape and form, and still (always until enlightenment?) so mysterious!
