After trying Aya as well as smoking Spice. 
Came up with a hypothesis on Ego And "Enlightenment" .
EGO
Body is like a Car. 
picture the average way of driving a car. basics, seat comfortable, mirrors, seat belt etc.
the notion of being Egotistical may very well be the above plus wearing a helmet and having an ejection seat in your car,safety goggles, Gloves, mouth guard, 4 cartoon like springs on each side of your car, . 
On DMT and even Aya. your driving this car using a gamepad/xbox controller ( vs your feet on brake n accelerator , or even hands on the lever etc ) , while u lay down on the hood of the car holding on tight, Soft trips might be like riding at 5-10 mph, hard ones can be like riding 30mph plus . 
your still operating the vehicle but just in a more "detached way". 
"Enlightenment thing" 
Well on smoked Spice well i can say its "Semi Permanent" effect but it feels as though "weightless weights were removed, or better yet  i was "spiritually overweight  and Smoked Spice was like ultimate Spiritual Fat burner lol . 
Enlightenment not exactly wise or awake but literally "weighing less" 
Even on Aya i remember after coming back from a trip i fell asleep , n woke up back in earth and felt like crust on my upper back n calves got removed and the Wings cold Fly again . 
Any other member come to something like this or can "draw comparisons " etc.
