Mulachara (Mūlacāra) (Fundamental Conduct) is a Jain text composed by Acharya Vattakera of the Digambara tradition,[1] around 150 CE.
[5] It is said to be derived from the original Ācārāṅga Sūtra and discusses the conduct of a Digambara monk.
The text is written in a dialect that is distinct but shares characteristics with Ardhamagadhi.
This suggests the existence of an ancient shared textual tradition between Digambaras and Śvetāmbara, one that likely split and differentiated later.
[1][6] Vasunandin wrote a Sanskrit commentary on the Mulacara, and it is titled Acaravrtti.
