“All the instructions of Bhagavad-gita are intended to awaken this pure consciousness, and therefore we find at the last stage of the Gita's instructions that Krishna is asking Arjuna whether he is now in purified consciousness. Purified consciousness means acting in accordance with the instructions of the Lord. This is the whole sum and substance of purified consciousness.” (Shrila Prabhupada, Bhagavad-gita, Introduction)
