Bhagavan Shri Krishna said: O Partha, please listen – when the mind is attached to Me and one practices yoga and takes full shelter of Me, then you will certainly be able to know Me.
Bhagavad Gita - Chapter 7 - Jnana-Vijnana Yoga - The Yoga of Knowledge and Realization
I will explain to you this knowledge and its realization. Once you understand this, there is nothing else in this world that remains to be known.
Amongst thousands of men, one may try to achieve perfection. Amongst those rare persons that endeavor for perfection, one may actually know Me.
Earth, water, fire, air, space, mind, intelligence and false ego – these are the eight different elements that constitute My material nature.
However, you should know that there is another nature, superior to this inferior nature. It is a conscious potency that consists of the living beings and maintains the universe.
Try to understand that all beings are manifest from these two sources and that I am the cause of the creation and annihilation of the entire universe.
Dhananjaya, there is nothing superior to Me. All things rest upon Me, just like jewels strung upon a thread.
I am the taste of water and the light of the sun and the moon, O son of Kunti. I am the syllable ‘om’ found in all the Vedas, I am the sound in space and I am the masculinity in man.
I am the original scent of the earth, I am the luster of fire. I am the life of all creatures and the penances of the performers of austerities.
O Partha, know that I am the original cause of all living beings. I am the wisdom of the wise and I am the power of the powerful.
