Some might argue with this, but with a goal of self-exploration I don't think smoked DMT is a good first choice.  Besides the intensity, which could put you off to psychedelics in general, the experience happens so quickly that self-exploration is difficult.  Pharma DMT would be somewhat better, but as azrael mentions, mescaline may be better still.  A low dose of LSD is good for self-analysis if you can find it, but as you may be aware "real" LSD is pretty hard to find these days and a lot what is sold as LSD is really something else.
