authorities voice diverse opinions. In 2005, an authority figure of Sikhism condemned same-sex marriage and the practice of homosexuality. However, many people in Sikhism do not oppose gay marriage. Hinduism is diverse, with no supreme governing body, but the majority of swamis opposed same-sex relationships in a 2004 survey, and a minority supported them. Ancient religious texts such as the Vedas often refer to people of a third gender known as hijra, who are neither female nor male. Some see this third gender as an ancient parallel to lesbian, gay, bisexual, transgender and intersex identities. Hinduism Hinduism does not have a central authority. Many Hindu sects have taken various positions on homosexuality, ranging from positive to neutral or antagonistic. Referring to the nature of Samsara, the Rigveda, one of the four canonical sacred texts of Hinduism says 'Vikruti Evam Prakriti' (Perversity/diversity is what nature is all about, or, What seems unnatural is also natural). A "third gender" has been acknowledged within Hinduism since Vedic times. Several Hindu texts, such as Manu Smriti and Sushruta Samhita, assert that some people are born with either mixed male and female natures, or sexually neuter, as a matter of natural biology (while at the same time there are examples of speaking negatively in regards to male homosexuality as shown by the Manu Smrititi and Arthashastra). In addition, each Hindu denomination had developed distinct rules regarding sexuality, as Hinduism is not unified and is decentralized in essence. Hindu groups are historically not unified regarding the issue of homosexuality, each one having a distinct doctrinal view. The Indian Kama Sutra, written around 150 BC, contains passages describing eunuchs or "third-sex" males performing oral sex on men. The text describes Kama as one of the three objectives to be achieved in life. Though it forbids the educated Brahmins, bureaucrats and wisemen from practicing Auparishtaka (oral sex). Similarly, some medieval Hindu temples and artifacts openly depict both male homosexuality and lesbianism within their carvings, such as the temple walls at Khajuraho. Some infer from these images that at least part of the Hindu society and religion were previously more open to variations in human sexuality than they are at present. Ayoni sex, which includes oral and anal sex, never came to be viewed as much of a sin like in Christianity nor a serious crime and could be practiced in some cases.
