Meaning

Yo, ditch the ego, the flexing, the arrogance, the thirst, the anger, and the need to own everything. If you're chill and not all possessive, then you're ready to become Brahman.

Commentary

OK, so like, ego? Forget that. Also, ditch the flexing, the arrogance, the thirst, the anger, and the need to hoard stuff. If you're chill and not all 'mine, mine, mine,' then you're basically ready to become one with the universe, or whatever.
