Yes. A non-Jain can अपनāe Jain Dharma by sincerely accepting the Jain path of Ahimsa, Satya, Asteya, Brahmacharya, and Aparigraha and beginning to follow Jain vows and practices according to their capacity.

In Jain tradition, becoming Jain is mainly about inner acceptance, right faith, right knowledge, and right conduct, not birth alone. A person may start by:

• respecting the Five Vows
• practicing non-violence in thought, word, and deed
• following vegetarianism and avoiding harm
• studying Jain principles
• gradually taking up Jain discipline under guidance

There is no single universal “conversion ceremony” in all Jain traditions, but a person can dedicate themselves to the Jain way of life sincerely.

The main thing is true devotion to Jain Dharma and a life of non-violence and self-discipline.
