Vedānta series 31
Sattva guṇa in association with the five basic elements is the cause for the formation of anthaḥkaraṇa or inner psychic organs. Tattvabodha next speaks about the combination of rajo guṇa leading to the formation of organs of action. Space and rajo guṇa is the cause for the formation of organ of speech, mouth; air and rajo guṇa forms organ of holding, hands; fire and rajo guṇa forms organ of locomotion, legs; water and rajo guṇa form procreative organ and earth and rajo guṇa forms organ of excretion. From the sum total of rajasic aspects and the gross elements, five prāṇa-s are formed. From the sum total of sattvic aspects and the gross elements anthaḥkaraṇa was formed, which was discussed in the previous chapter.
Sattva guṇa and five elements give rise to organs of perception or jñānendriya-s and rajo guṇa and five elements give rise to organs of action or karmendriya-s. Sattva guṇa in conjunction with the all the five elements put together form the anthaḥkaraṇa and rajo guṇa in combination with the all the five elements put together form the five types of prāṇa-s. Tanmātra-s, the subtlest form of the elements in association with the three guṇa-s form the causal body and knowledge and action faculties in association with the three guṇa-s form the subtle body.
After having created the organs of perception and action and in order to ensure their movements, the five prāṇa-s are created. Prāṇa-s is like the electricity, without which the electric gadgets cannot function. Prāṇa-s is the functional aspect of all the beings, without which the organs of actions cannot function.
