According to the Nirukti, or the Vedic dictionary, sankhya means that which describes phenomena in detail, and sankhya refers to that philosophy which describes the real nature of the soul. And yoga involves controlling the senses. Arjuna's proposal not to fight was based on sense gratification. Forgetting his prime duty, he wanted to cease fighting because he thought that by not killing his relatives and kinsmen he would be happier than by enjoying the kingdom by conquering his cousins and brothers, the sons of Dhrtarastra. In both ways, the basic principles were for sense gratification. Happiness derived from conquering them and happiness derived by seeing kinsmen alive are both on the basis of personal sense gratification, for there is a sacrifice of wisdom and duty. Krsna, therefore, wanted to explain to Arjuna that by killing the body of his grandfather he would not be killing the soul proper, and He explained that all individual persons, including the Lord Himself, are eternal individuals; they were individuals in the past, they are individuals in the present, and they will continue to remain individuals in the future, because all of us are individual souls eternally, and we simply change our bodily dress in different manners. But, actually, we keep our individuality even after liberation from the bondage of material dress. An analytical study of the soul and the body has been very graphically explained by Lord Krsna. And this descriptive knowledge of the soul and the body from different angles of vision has been described here as sankhya, in terms of the Nirukti dictionary. This sankhya has nothing to do with the sankhya philosophy of the atheist Kapila. Long before the imposter Kapila's sankhya, the sankhya philosophy was expounded in the Srimad-Bhagavatam by the true Lord Kapila, the incarnation of Lord Krsna, who explained it to His mother, Devahuti. It is clearly explained by Him that the Purusa, or the Supreme Lord, is active and that He creates by looking over the prakrti. This is accepted in the Vedas and in the Gita. The description in the Vedas indicates that the Lord glanced over the prakrti, or nature, and impregnated it with atomic individuals souls. All these individuals are working in the material world for sense gratification, and under the spell of material energy they are thinking of being enjoyers. This mentality is dragged to the last point of liberation when the living entity wants to become one with the Lord. This is the last snare of maya or sense gratificatory illusion, and it is only after many, many births of such sense gratificatory activities that a great soul surrenders unto Vasudeva, Lord Krsna, thereby fulfilling the search after the ultimate truth.
