Self-experimentation as I suggest -- an age old tradition in the scientific sphere -- is simply meant to reorient the person towards a broader understanding of the dimensions possible within the tryptamine-consciousness experience. I would never claim that personal experience alone is enough to quantify anything beyond mere opinion; that&#x27;s where a formal control-based study steps in. But what it can do is quite dramatically open the mind to possibilities that were previously thought impossible or inconceivable -- a valuable practice.
