The question never enters the mind of the people; why are there so many contradictory religions, opinions, theories, authorities, scriptures and men? Non-dual wisdom is not theoretical wisdom. Philosophic speculation is not non-dual truth.
Pursuit of truth does not belongs to any religion, because it inquiries into the value of religion just as it inquiries into the value of the whole physical existence. Because pursuit of truth is so troublesome, people don't want to be bothered with it, but remain content with mysticism or religion, where the need of thinking is absent. Non-dual wisdom comes only by transcending them all for it depends on un-contradiction.
Inquiry will always look thoroughly into all sides of a question, whether it is concerning a material or a spiritual matter, and decide upon it.-FORMLESS PATH
