In Jainism, the core principle is ahimsa (non-violence), which means not causing harm to any living being in thought, word, or deed. While watching pornography may not cause direct physical harm to others, Jain ethics also emphasize the importance of controlling passions (kashayas) such as attachment, desire, and sensual pleasures, as these can disturb the mind and hinder the path to liberation (moksha).

Indulgence in sensual pleasures, including viewing pornography, is generally discouraged in Jainism because it can strengthen passions (raag and dwesh) and attachment to the material world. Jain scriptures encourage cultivating self-restraint (samyam) and purity of thought (samyak bhav) to progress on the spiritual path.

Ultimately, Jain teachings suggest that one should strive to purify the mind and practice restraint in all aspects of life, including avoiding activities that may increase attachment or disturb inner peace.
