Synopsis INDIA-before the advent of Muslims and coming of British Colonials-had an outlook on sexuality different from what Islam preached and Christianity practised. The book first of its kind in Indian anthropology aims to clear the cloud of mystique enveloping the minds of the Indian youth on the subject of sexuality. It is intended for those who desire to understand themselves. The basic biological differences between male and female have been elaborated scientifically and systematically. The morpho-physiological differences have been highlighted since these are intrinsic in comprehension of sexuality. The journey from oestrus to menstruation has been viewed as an evolutionary strategy of nature. Sexual behaviour of human beings has been typified. The mystique of sex and religion has been unravelled by elaborating upon the basic religious' concepts regarding creation and procreation. The inherent meaning behind phallic worship and the concept of urdvaretas has been explained. Siva, Vamdeva, Kamdeva have been brought out from the clouds of mystery and presented before the readers. The duality and contrast existing in our culture is also explained. The case studies from the tribal world have been depicted to elicit the variety and diversity of human sexuality.
