Religion in India involves washing parts of the body that are generally exposed to dirt or dust.

Almost one-third of Indians practice lacto-vegetarianism. Vegetarianism is less common amongst Sikhs and almost uncommon amongst Muslims, Christians, Bahá'ís, Parsis, and Jews.

Digambara texts such as the "Samayasāra" and the "Pravacanasāra". Other prominent "Acharyas" of this tradition were, Virasena (author of a commentary on the "Dhavala"), Samantabhadra and Siddhasena Divakara. The "Satkhandagama" and "Kasayapahuda" have major significance in the "Digambara" tradition. Relics found from Harrapan excavations such as seals depicting "Kayotsarga" posture, idols in "Padmasana" and a nude bust of red limestone, give insight into the antiquity of the "Digambara" tradition. The presence of gymnosophists (naked philosophers) in Greek records as early as the fourth century BC, supports the claim of the "Digambaras" that they have preserved the ancient "Śramaṇa" practice.
