The Krishna Consciousness has nothing to do with the protagonist Krishna of Mahabharata. However, here the term Krishna is only a symbolic representation of utter divinity in the psyche of the Hindus. The Krishna Consciousness is basically, a mental state of transcendence, which can similarly be called as “the Christ Consciousness” or “the Buddha Consciousness” or even “the Naskar Consciousness”. Buddha hailed it as Nirvana, while Christ, upon experiencing it, said to his pupils, “I and the Father are one.” Upon emerging from this extraordinary state of Absolute Oneness, the Self turns into Krishna – it turns into Christ – it turns into Buddha.
So it is our request that you try to study Bhagavad-gītā as it is. Don't try to distort it by your so-called education. Try to understand Kṛiṣṇa as He is saying. Then you will be benefited. Your life will be successful.
