Yes, a non-Jain can practice Jainism. Jainism is an inclusive and universal religion that emphasizes the principles of non-violence (ahimsa), truth (satya), non-stealing (asteya), celibacy (brahmacharya), and non-possessiveness (aparigraha). These teachings are open to anyone, regardless of their background or previous beliefs.

Many people who are not born into Jain families adopt Jain practices such as vegetarianism, meditation, and ethical living. Jainism does not require formal conversion; instead, it encourages individuals to follow its principles sincerely and to the best of their ability. The path of Jainism is about personal transformation and spiritual growth, which is accessible to all who are interested.
