In Jain Dharma, if you have taken a household vow of celibacy (brahmacharya) until marriage, masturbation is not allowed. It is considered a form of sexual activity and a breach of that vow.

Key Jain points:

1. Brahmacharya = control over sexual desire

- Not just “no intercourse with someone else”, but restraint from all deliberate sexual indulgence. - That includes masturbation, pornography, and intentionally arousing sexual thoughts and fantasies. ( jainknowledge.com)

1. Why masturbation is discouraged in Jainism

- It excites passions (kashāyas) like lust and attachment. - Increases dependence on sensual pleasure instead of inner peace. - Strengthens karmic bondage instead of reducing it. ( jainknowledge.com)

1. Layperson vs monk

- For monks/nuns: any sexual thought or act, including masturbation, is a clear violation of Mahāvrata Brahmacharya. - For laypeople: ideal conduct is - complete celibacy before marriage, - fidelity and restraint within marriage. Masturbation is viewed as a lapse in self‑control and against the spirit of brahmacharya. ( jainknowledge.com)

1. If you are struggling

- Do pratikraman (confession and repentance) when you slip. - Reduce triggers: erotic content, stimulating talk, late‑night idleness, wrong company. - Strengthen the mind with sāmāyik, svādhyāy (study), and remembering the goal of inner purity. ( jainknowledge.com)

So, within a Jain vow of celibacy till marriage, masturbation goes against that vow and should be avoided, with gentle but firm effort and regular pratikraman if you fall.
