What is PSYCHONAUTIC?

Our discussion keeps returning to how we can define something as 'psychonautic' in distinction from 'recreational' modes of altered states or experiences of consciousness expansion wherein that was not the original intent.  

Does it have to be the intent of the individual to explore their conscience?  If so, what if the original intent was to just have fun and the experience becomes mind-opening instead/as well?  Or what if it has expanded consciousness upon reflection, after the fact?  Or what if you subconscious was doing the work but your mind was changed retroactively?

Here is something to consider: the term 'psychonaut' refers to someone who journeys/travels through inner space in order to explore consciousness (i.e., they explore the mind via the mind, not by external means).  The idea of 'traveling' connotes a certain degree of intent.  When you say you're traveling somewhere, it means you have intent to go somewhere, even if you don't know where that is.  To me then, that intent is inherent in the term, it's not just a characteristic.  

However, I think it's possible to begin an experience either accidentally (think of Albert Hoffman's accidental ingestion of LSD) or for other purposes and have it become psychonautic.  But this would imply that during the trip something changed/happened that reoriented your mind towards itself and that from there you approached the altered state differently - as a medium within which the mind could be explored - this is where it becomes psychonautic.  Exploring/journeying = intent (right?...) This can get painfully metaphysical very fast considering the double-register of consciousness this experience entails, which is why Travis and Eva's diagram seems useful...

You can still have extremely profound inner experiences that aren't psychonautic, and this doesn't devalue them in anyway.  But there is a difference between exploring the mind and being experienced.
