Sbg 14.10 etradi
English Translation of Ramanuja's Sanskrit Commentary By Swami Adidevananda 14.10 Even though all the three Gunas of Sattva etc., are associated with the nature of the self conjoined with Prakrti in the form of body, yet owing to the dominance of previous Karmas and the differences in the food nourishing the body, Sattva etc., preponderate or are subdued by turn. Sometimes Sattva preponderates prevailing over Rajas and Tamas; sometimes Rajas preponderates prevailing over Tamas and Sattva, and sometimes Tamas preponderates prevailing over Rajas and Sattva.
He teaches that this changing preponderance of the Gunas can be inferred from the knowledge of the effects produced by them.
