Why do erotic scuptures appear on the religious monuments??

The early scholarship associated the sculpture were carved to  protecting the monuments from the lighting and thunder or evil eye or to attract the tourist  , secondly there is a disregard for other sects like Kuala kapilaka and other . thirdly  to teach the sex education as people are ashamed of sex so sexuality and religion could be enter linked .these theories have been negated by scholar . The theory which is associated to erotic sculptures is the link with the tantric cult.

There is no mentioning of the temples of Khajuraho in any text as pilgrimage centre. The tantric as well as the prunes are silent about Khajuraho. There s no evidence if patronage of the chandelle to the tantrums.

The predominance to the erotic sculpture could to trace by Pramod Chandra as an influence of Kuala kapilaka, while L.k. Tripati suggests that there were the Kuala kapilaka by the digimbar monks.

Devangana deasi argues that the panchayantana Vaishnava of the Vaikuntha cannot be associated to the Kuala- kapilaka.  There is a tantric influence on the Lakshmana temple is enshrining with the three faces Vishnu, varah and narishma that forms Vaikuntha. It is an important of pancharactic pantheon of the tantrisim. The kasimargara scholar and the padma tantra and isvara samhita mention Tanta Tara School Vishnu as Vaikuntha. The image is said to come from Bhota the modern Tibet .the worship of the panchantratic image of Vishnu obtained from the tantric religion. But the inscription which as on the temple tell a different story. As it upheld the idea of the puranic cult as the king is said to protect the three Vedas and maintain the prosperity of the Brahman. therefore on can suggest that the religious attribute of the temple at Khajuraho had both puranic as well as tantric influence in it .as  Devangana Desai suggest that there is a prevalence of the school of samarta worship , this form of worship is a mixture of the  puranic as well tantric religion.

Richard Lannoy explains the reason for the erotic sculpture on the religious monument with a Buddhist understanding. The Buddhists philosophy of middle path condemned passion, and excess. It prohibited women in it initial stage but later on women were included in it. He calls it the influence of the Sahaja cult.

He further suggests the sex life in the religious setting is more dedicated to fertility. The Upanishad also uses the metaphor of the sexual freedom for the experience of the other. The Gita Govind also has a great variety of the erotic spiritual realization. The religious language of the erotic cannot be developed without the erotic metaphor or erotic imagery in the religious literature of India. The sexual imagery was present in cult like tantric and Sahaja which as religious connotations.
