What did you understand about the cosmic joke?

Yeah i know is impossible to describe it aside from a very layered mindfuck yet trivial joke, but i believe that if you get it is presented to you in some particular way

Some people say is like realizing why nothing matters...

In my case I was having a bit of a challenging trip, (one of my first trips) and i was like, damn i need to let go, i need to let go, i need to let go... After some time I gave up on letting go, aka i let go. I begin to laugh for 10 minutes straight, like I wasnt realizing that letting go is not about feeling ok, but being aware of how you feel and, just that. Like even if you are not accepting some reality in your life, the moment you become aware of that and you choose to not fight the fact that you are not accepting, you would accept that therefore be on a stage of acceptance. That mindfuck felt extremely blissful and good, was the first time in my life that i fully let go.
