Welcome

Definitely enjoyed your trip writeup
Advaita Vedanta's powerful, the whole of it. Great reading, always seemingly relevant to life in many of the things described in all the various texts, not to mention how it carries many similarities to some of the things felt/experienced during a strong tryptamine experience imo [or really any peak-type psychedelic experience].
Yeah, you're definitely not alone, the experience as a whole eludes description imo, the thing in and of itself doesn't fall within the netting of rationale and compartmentalization. Any ideals or thoughts on the matter prior-to typically are subsumed almost immediately with a good dose administered decently well [as you found out

].
Cheers
