You have to grow from the inside out. None can teach you, none can make you SPIRITUAL. There is no other teacher but your own SOUL.

"Whosoever enjoys continuous consciousness lives conscious each and every instant, not only in the physical world, but also in the superior worlds.

This present humanity is ninety-seven percent in the subconscious. Therefore, this humanity profoundly sleeps, not only in this physical world, but also in the supra-sensible worlds during the sleep of the physical body, as well as after death."

~Samael Aun Weor, The Elimination of Satan's Tail.
