Every Hindu knows that astrologers try to fix the caste of every boy or girl as soon as he or she is born. That is the real caste - the individuality, and Jyotisha (astrology) recognises that. And we can only rise by giving it full sway again. This variety does not mean inequality, nor any special privilege.
Swami VivekanandaAll action of Sattva, a modification of Prakriti characterised by light and happiness, is for the soul. When Sattva is free from egoism and illuminated with the pure intelligence of Purusha, it is called the self-centred one, because in that state it becomes independent of all relations.
