Tantra (Sanskrit: loom), tantric yoga or tantrism refers to any of several esoteric traditions rooted in Hindu and Buddhist philosophy. Extolled as a short-cut to self-realization and spiritual enlightenment by some, left-hand tantric rites are often rejected as dangerous by most orthodox Hindus.
There are two paths in Tantra: One is the Right-Hand path or Dakshinachara (also known as samayachara) and the other is the left-hand path called vamachara. The latter is associated with many ritual practises that go against the grain of mainstream Hinduism, including sexual rituals, alcohol and other intoxicants, animal sacrifice and flesh-eating.
Homo sapiens sexuality is primarily a social behavior, learned and shared. Human sexuality can only be understood as part of the social life of humans, governed by the same rules of culture and learning as other behaviors and meanings. In the same way that we cannot speak or walk on two feet without learning how, so too is human sexuality formed by the complex social environment in which we live. Reproduction is one function of sexuality, but only one among many. Human physiology makes sexuality possible, but it does not predict sexual behavior in any way.
The complexity of sexual behaviors in humans is produced by our high intelligence and complex societies, rather than being governed by instinct as in most other animals. Some would argue that much human sexual behaviour is not diven by wisdom.
Human sexuality has aspects relating to health, pleasure, and social interactions such as legal and religious taboos.
