nature of the Self: theory, image & archetype
The Katha Upanishad (1.11-13) speaks of Purusha (Cosmic Person):
“That the Adorable One [Bhagavat] exists in the faces, the heads, the necks of all, he dwells in the cave (of the heart) of all beings, he is all-pervading, therefore he is the omnipresent Shiva.”
“That person [purusha] is the great lord; he is the mover of existence. He possesses that purest power of reaching everything, he is light, he is undecaying.”
“The purusha, who is of the size of a thumb, resides in the body … The purusha who is the size of a thumb is a light without smoke.”
In Symbols of Transformation, Carl Jung speaks of the ‘Primordial Person’ (Purusha), drawing upon a passage from the Shvetashvatara Upanishad:
“Without feet, without hands, he moves, he grasps; eyeless he sees, earless he hears; he knows all that is to be known, yet there is no knower of him. Men call him the Primordial Person, the cosmic man. Smaller than small, greater than great ….” (cited in CW5, para. 182, emphasis added).
These ancient Hindu texts point to the sacred nature of the divine, both transcendent and immanent. “No bigger than a thumb,” God dwells in the heart as the Self.
