Thankyou for response Chris,
i know of no teaching that says cast aside the bible or the koran or the bhagavad gita. God teaches through these books and the knowledge is carried through the ages by various spiritual masters. These books will never be out of fashion for they teach a way of life we all recognise inside. We also know how to recognise bogus gurus and charlatons through these books in that if a teacher does not practice what is stated they should not be accepted as an authority on these matters.
Your friend,
