As Adam (17)

“He is my self within the heart, smaller than a corn of rice, smaller than a corn of barley, smaller than a mustard seed, smaller than a canary seed or the kernel of a canary seed. He also is my self within the heart, greater than the earth, greater than the sky, greater than heaven, greater than all these worlds.” – The Upanishads

As Adam (13)

“Different from this, which consists of breath, is the other, the inner Self, which consists of mind. The former is filled by this. It also has the shape of man. Like the human shape of the former is the human shape of the latter.” – The Upanishads
