All the scriptures hold the form, time and space as reality. If they hold form, time and space as reality the universe is automatically becomes reality. If the universe is considered as a reality than birth, life death will be experienced as reality. If birth, life and death is taken as reality than it is impossible to cross the threshold of duality. If duality remains as a reality than ignorance will prevail unchecked. If ignorance prevails than illusion will prevail as reality.
Deeper self-search reveals the fact that, religious and yogic pursuit and pursuit of truth are not the same. The religious yogic pursuit is egocentric whereas the pursuit of truth is soul-centric.
The scriptures and theories and teaching based on the ego are not the yardstick. Using them as yardstick to understand and assimilate the truth will lead one towards pursuit of arguments. Seeker of truth has to discover on his own, the truth of his true existence by inquiring “what is mind?” and “what is substance of the mind?” “What is the source of the mind?” and move forward.
The wisdom consists in knowing the truth, that everything (mind or physical existence) is consciousness. Freedom (truth) is always there yet one does not know it. But to those whose reason is turned away from physicality and who have attained the serenity of the soul/self (consciousness) are quite near to the ultimate truth.
To think once own body and his experience of the world is an illusion is difficult matter, unless one realizes the self is not physical but it is formless soul it is difficult to have glimpse of truth.
When one realizes the fact that, the self is not physical but the formless soul, naturally the body and universe becomes illusion.
Anyone who has inner urge, humility and patience is qualified for Self-knowledge or Brahma Gnana or Atma Gnana. A Gnani tries to lead the seeker of whatever level, to the goal of the true existence.
