Jainism [SEP] Introduction
Devout Jains take five main vows: "ahiṃsā" (non-violence), "satya" (truth), "asteya" (not stealing), "brahmacharya" (sexual continence), and "aparigraha" (non-possessiveness). These principles have affected Jain culture in many ways, such as leading to a predominantly vegetarian lifestyle. "Parasparopagraho Jīvānām" (the function of souls is to help one another) is its motto and the "Ṇamōkāra mantra" is its most common and basic prayer. Jain dharma is one of the world's oldest religions and has two major ancient sub-traditions, Digambaras and Śvētāmbaras, with different views on ascetic practices, gender and which texts can be considered canonical; both have mendicants supported by laypersons ("śrāvakas" and "śrāvikas").
