The Supreme Lord said: O best among men, please listen as I describe to you how the living entity attains a particular nature by association with individual guṇas in their unmixed forms. In the Twenty-fifth Chapter, the functions of the guṇas and various objects affected by the guṇas, as well as objects beyond the guṇas are described in sequence. The functions of the three guṇas are described because as long as one does not conquer the actions of the three guṇas one continues to identify with the body even if one can distinguish the body from the ātmā by Sāṅkhya. The guṇas are mixed but I will describe the guṇas not mixed with each other. Please understand as I speak (śaṁsataḥ) how a person is affected by each guṇa.
