When the Upanishad says: the human goal is to acquire Self-Knowledge or Brahma Gnana or Atma Gnana and they indicate the personal gods, scriptures, worship and rituals are not the means to Self –Knowledge or Brahma Gnana or Atma Gnana, then why anyone should indulge in it. The religion, concept of individualized god and scriptures are the greatest obstacle to realize non-dual truth or self-reali zation, because they are based on false self. The seeker of truth has to search the ultimate truth without losing himself in the labyrinths of philosophy, through deeper, inquiry, analysis and reasoning and assimilate and realize it.
That is why Sage Sri Sankara, indicated in Bhaja Govindam says: - [Jnana Viheena Sarva Mathena Bajathi na Muktim janma Shatena] - one without knowledge does not obtain liberation even in a hundred births, no matter which religious faith he follows.
Then it is no use going roundabout way, trace the Brahman which is the formless substance and the witness of the universe, which is in the form of mind. By tracing the source of the mind or universe one will be able to realize the Brahman. --FORMLESS PATH
