Ancient Indian texts describe achievement of Dharma (religion), Arth (Wealth), Kama (pleasures) and Moksha (salvation) as four basic goals governing the three distinct stages of human life – childhood, youth and old age. Vatsyayana instructs that a sensible and righteous man must segregate his lifetime wisely so that he can practice religion, wealth as well as carnal pleasures. He, however, also warned that humans should be careful about not letting one infringe or encroach upon the other. And it is basically the information about carnal pleasures that Vatsyayana provided in the Kamasutra.
