Additionally, self-discovery is not inherently individualistic. The most powerful discovery I made during my first trip was that I would not be who I am (self-discovery) without the influence of the many, amazing people I've had the good fortune of knowing (anti-individualistic). This understanding came with overwhelming gratitude and a desire to become closer with more people in my community.
In general psychedelics strip away your ego such that your self appears illusory. I've never met anyone whose takeaway from psychedelics was individualistic.
