Supersoul & Paramatma
The Supersoul, or Paramatma, is a partial representation of the Supreme Person who oversees and sanctions all that goes on within the material world. Paramatma is within each atom and each living entity, accompanying the individual atma (soul) throughout each of our lifetimes in material bodies, and helping us fulfill our individual destinies and desires.
In the Thirteenth Chapter of Bhagavad-gita, Krishna explains how He, as the Supersoul, simultaneously exists in the hearts of all beings as the well-wishing friend of everyone, the witness to all activities, the maintainer of all things, and the supreme controller within the universe.
The top painting shows how Krishna is present in every living entity. The middle painting ("Read More" view) illustrates the Upanishads' allegory of Supersoul and the individual soul as two birds.
