There are many posts like this, for more information on DMT may I refer you to erowid.org
Yes DMT can be very spiritual as for being able to reach "enlightenment" I dont know, but it can be enlightening. Because it is a psychedelic nothing can be said about it with any object certainty as it effects everyone differently. If feel ready to try it and have a good amount of psychedelic experience then go for it, just remember dose (if you are extracting it and have crystals then get a mg scale) set and setting.
