i know this was addressed to dariel, but may i offer some information??
as far as your experience with hard drugs... there may be some affect on the spirit from this, but i do not believe the affect will be very damaging. after all, drug experiences are experience (possibly profound??)!! and experience is what ITS all about. positive or negative, it is still experience, and experience is VALUABLE, no matter what.
all have infinite potential. one is not limited in this potential due simply to some experiences (drug induced or otherwise).
you breath air, is the air totally clean?? will this limit you?? i think not!!
all that you may progress toward is within you, the only limits set before us, are self induced, "mental games" if you will.
when one realizes this (some must realize this dozens or hundreds of times before application begins) it is very exciting, and the universe opens up.
i hope you can understand my writing (im far from articulate):>)
