Kapila Rishi (Sk.). A great sage, a great adept of antiquity; the author of the Sankhya philosophy.

Sânkhya (Sk.). The system of philosophy founded by Kapila Rishi, a system of analytical metaphysics, and one of the six Darshanas or schools of philosophy. It discourses on numerical categories and the meaning of the twenty-five tatwas (the forces of nature in various degrees). This “atomistic school,” as some call it, explains nature by the interaction of twenty-four elements with purusha (spirit) modified by the three gunas (qualities), teaching the eternity of pradhâna (primordial, homogeneous matter), or the self-transformation of nature and the eternity of the human Egos.

Sânkhya Yoga (Sk.). The system of Yoga as set forth by the above school.

Tattwa (Sk.). Eternally existing “That”; also, the different principles in Nature, in their occult meaning. Tattwa Samâsa is a work of Sânkhya philosophy attributed to Kapila himself.
