For this reason the fourth plane is one of the most difficult and dangerous to cross. The pilgrim is never spiritually safe, and his reversion is always possible until he has successfully crossed the fourth plane and arrived at the fifth. Here the incessant activity of the lower intellect comes to a standstill. The pilgrim does not think in the ordinary way, and yet he is indirectly a source of many inspiring thoughts. He sees, but not with the physical eyes.
Mind speaks with mind, and there is neither worry nor doubt.
But if he moves on, he perceives his mistake and advances to the sixth plane. Now the pilgrim sees God as directly and as clearly as an ordinary person sees the different things of this world. This continual perception and enjoyment of God does not suffer a break even for an instant. Yet the wayfarer does not becomes one with God, the infinite. If the pilgrim ascends to the seventh plane, he experiences the last merging, which is called Fana-Fillah , or the final annihilation of the self in God.
