Originally one, the Absolute, Brahman, comes to be known as threefold, manifesting itself as the three modes of material nature — goodness, passion and ignorance. Brahman further expands its potency, and thus the power to act and the power of consciousness become manifest, along with the false ego, which covers the identity of the conditioned living being. Thus, by the expansion of the multipotencies of the Absolute, the demigods, as the embodiment of knowledge, become manifest, along with the material senses, their objects, and the results of material activity, namely happiness and distress. In this way the manifestation of the material world takes place as the subtle cause and as the material effect visible in the appearance of gross material objects. Brahman, which is the source of all subtle and gross manifestations, is simultaneously transcendental to them, being absolute.
