In the ninth chapter of the Bhagavad Gita Bhagavan Sri Krishna gives emphasis to revealing the non-dual vision of reality. It is called Raja Vidya, the ‘King’ of knowledge, because knowing this alone, one can be free from ignorance. It is caleed Raja Guhya, the ‘king’ of secrets, because one never suspects that it is oneself.
