When the Self not the body then why you are thinking of the brain and the heart.+

The Yoga Sastras say that the Sahasrara or brain is the seat of the 'Self’. The Purusha Sukta declares that the Heart is its seat. When the 'Self’’ is not the body then why you are thinking of the brain and the heart. 

Mundaka Upanishad: -  The deathless 'Self' has neither caste nor race, Neither eyes nor ears nor hands nor feet. Sages say this Self is infinite, everlasting, and changeless. 

The Soul, the 'Self’ is ever formless, timeless, and spaceless existence. The ‘Soul is not within the body but the world in which you exist is within the Soul. 

When you realize the world in which you exist is created out of the Soul, which is present in the form of the consciousness then you will realize the world in which you exist is merely an illusion created out of the Soul, which is present in the form of the consciousness.

That is why Sage Sankara:~ VC~.63: "Without knowing and examining the external world, one can’t know the Truth, as the idea that the external world exists, won't go. It can go only by an inquiry into the nature of the external world.

Mundaka Upanishad 1.3:~ complete knowledge includes knowledge of the phenomenal world, the spirit behind it, and the source of both of them. When the cause of all causes becomes known, then everything knowable becomes known, and nothing remains unknown is Gnana.”

It takes time for the seeker to gain the perfect understanding of ‘what is the truth’ and ‘’what is untruth’.

As you raft upon which you cross the swift river to get to the other side; once you are on the other side of the shore; there is no longer any need to carry the raft. The far shore is the reality when you reach it, you can see quite clearly that there was never any river at all. : ~ Santthosh Kumaar
