Bhagavad Gita says: ~ “Don't unsettle the minds of the ignorant by revealing the esoteric truth."+

Advaitic Gnana was not written down but was imparted orally to the chosen few. Thus, religion was given to the ignorant populace, and the knowledge of the Spirit was given to only a selected few.

Thus, we find traces of the knowledge of the Spirit in religious books in the form of parables.

The Bhagavad Gita says: ~ Among thousands of men, scarcely one strives for perfection; and of those who strive and succeed, scarcely one knows the ‘Self’ in truth.

The path of wisdom attracts only those who are in search of truth and they appreciate it greatly. The ignorant are not spiritually mature the receive Self-knowledge or Brahma Gnana or Atma Gnana.

The ignorant indulge in argument provocation and personal attack, which hinder their own realization of the ultimate truth or Brahman.

That is why Jesus said: - Do not throw your pearls before pigs, lest they trample them underfoot and turn to attack you. (Matthew -7:6) 

~ Jesus meant knowledge of God, the Spirit or Knowledge of God or Self-knowledge or Brahma Gnana or Atma Gnana.

Bhagavad Gita says: ~ “Don't unsettle the minds of the ignorant by revealing the esoteric truth."

Katha Upanishad says: ~ This Atman is attained by him alone whom It chooses. (II -23-P-20)

Thus, those who have taken the path of wisdom are chosen ones. The chosen one will get the grace of the Soul the inner Guru. The path of wisdom is the Soulcentric path, whereas all other paths are egocentric. All egocentric paths lead to hallucination.

The Soul, the 'Self' reveals ‘what is real’ and ‘what is unreal” when the seeker is receptive and ready.

This is the bondage that you are stuck up to the ‘I’ centric teaching. ‘I’ centric teachings are lower knowledge meant for lower stages.

The seeker has to ignore these ‘I’ based teachings and search for higher knowledge. ... Such teachings are unsafe rafts for crossing the ocean of ignorance. Doomed to shipwreck are those who try to cross the ocean of ignorance on these poor rafts. Ignorant of their own ignorance, yet wise in their own esteem, these deluded people proud of their vain learning go round and round like the blind led by the blind.

The Soul, the innermost Self is verily Brahman (God), being equanimous, quiescent, and by nature absolute Existence, Knowledge, and Awareness. The Soul is not the ‘I’ which is non-existence itself. The realization of this truth is called Self-knowledge by the Sages of truth.

There is nothing that exists prior to consciousness. The ‘I’ ceases to exist without consciousness. The Soul, which is present in the form of consciousness, is the ultimate truth or Brahman. : ~ Santthosh Kumaar
