Shilpa Shastras (Sanskrit: शिल्प शास्त्र śilpa śāstra) literally means the Science of Shilpa (arts and crafts). It is an ancient umbrella term for numerous Hindu texts that describe arts, crafts, and their design rules, principles and standards. In the context of Hindu temple architecture and sculpture, Shilpa Shastras were manuals for sculpture and Hindu iconography, prescribing among other things, the proportions of a sculptured figure, composition, principles, meaning, as well as rules of architecture.
Sixty-four techniques for such arts or crafts, sometimes called bāhya-kalā "external or practical arts", are traditionally enumerated, including carpentry, architecture, jewellery, farriery, acting, dancing, music, medicine, poetry etc., besides sixty-four abhyantara-kalā or "secret arts", which include mostly "erotic arts" such as kissing, embracing, etc.
