Digambara monk the Jain text, "Dravyasamgraha": Digambara monks are also called "nirgrantha" which means "one without any bonds". The term originally applied to those of them who were on the point of attaining to omniscience, on the attainment of which they were called "munis". Rishabhanatha (the first "tirthankara") is said to be the first "Digambara" monk of the present half cycle of time ("avasarpini"). 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. "Acharya" Bhadrabahu, "Acharya" Kundakunda are two of the
Jain literature from the first "tirthankara" Rishabhanatha. The "Digambara" sect believes that there were 26 "Agam‑sutras" (12 "Ang‑agams" + 14 "Ang‑bahya‑agams"). However, they were gradually lost starting from one hundred fifty years after Lord Mahavir's "nirvana". Hence, they do not recognize the existing Agam-sutras (which are recognized by the "Svetambara" sects) as their authentic scriptures. In "Digambara" tradition, two main texts, three commentaries on main texts, and four "Anuyogas" (exposition) consisting of more than 20 texts are followed. These scriptures were written by great "Acharyas" (scholars) from 100 to 1000 AD using the original "Agama Sutras" as the basis for their work.
