"Inclusion in one of these four castes originally depended not on a man's birth but on his natural capacities as demonstrated by the goal in life he elected to achieve," an article in East-West for January, 1935, tells us. "This goal could be (1) kama, desire, activity of the life of the senses (Sudra stage), (2) artha, gain, fulfilling but controlling the desires (Vaisya stage), (3) dharma, self-discipline, the life of responsibility and right action (Kshatriya stage), (4) moksha, liberation, the life of spirituality and religious teaching (Brahmin stage). These four castes render service to humanity by (1) body, (2) mind, (3) will power, (4) Spirit. "These four stages have their correspondence in the eternal gunas or qualities of nature, tamas, rajas, and sattva: obstruction, activity, and expansion; or, mass, energy, and intelligence. The four natural castes are marked by the gunas as (1) tamas (ignorance), (2) tamas-rajas (mixture of ignorance and activity), (3) rajas-sattva (mixture of right activity and enlightenment), (4) sattva (enlightenment). Thus has nature marked every man with his caste, by the predominance in himself of one, or the mixture of two, of the gunas. Of course every human being has all three gunas in varying proportions.
