"Brahman, being full of opulences, is understood to have manifold energies, and all these energies are classified under three headings under the authority of Viṣṇu Purāṇa (6.7.60), which says that the transcendental energies of Lord Viṣṇu are primarily three. His spiritual energy and the energy of the living entities are classified as superior energy, whereas the material energy is an inferior one which is sprouted out of ignorance.
"The energy of the living entities is technically called kṣetrajña energy. This kṣetrajña-śakti, although equal in quality with the Lord, becomes overpowered by material energy out of ignorance and thus suffers all sorts of material miseries.
