Ignorance makes one experience the duality (universe or waking) as reality.

The nature of the soul, the innermost self is formless and non-dual. Non-duality is oneness is incomprehensible and so any communication about it can only be an interpretation of the ideas based on the waking entity or ego, which is the false self within the false experience.

Ignorance generates doubts and confusion. Ignorance makes one experience the duality (universe or waking) as reality. Ignorance makes one view and judge on the standpoint of false physical self or ego. Whatever is based on false physical self or ego is bound to be falsehood because everything is viewed and judged believing the duality as reality. Thus, one is unable to think beyond duality.

Deeper understanding and assimilation is required for Self-Realization. It becomes difficult to understand and communicate about the oneness on the base of false self. Thus rectifying the true base is necessary from form base to formless base to understand and assimilate and realize the non duality. -FORMLESS PATH
