In Jainism, Chaudas (the 14th day of each lunar fortnight) is considered a spiritually significant day often dedicated to increased vigilance in one's conduct, introspection, fasting, and spiritual activities. Lay followers (śrāvaks and śrāvikās) are encouraged to observe greater discipline, including celibacy (brahmacharya), restraint, and avoidance of indulgence in sensual pleasures on such days.

Engaging in intimate physical acts like making out is considered indulgence in sensual pleasure (kaam), which is generally discouraged in Jain philosophy, especially on spiritually important days like Chaudas. Such actions are believed to increase passions (kashayas), which bind karma to the soul and impede spiritual progress.

Committing such acts on Chaudas is seen as a greater lapse in self-restraint compared to ordinary days, as the expectation for heightened discipline is higher. While Jainism teaches forgiveness and the possibility of repentance (pratikraman), it also emphasizes mindfulness and adherence to vows, especially on days meant for spiritual upliftment.

In summary, according to Jain teachings, making out on Chaudas is considered a violation of self-restraint and increases karmic bondage, with added seriousness due to the sanctity of the day. Repentance and a sincere resolve to observe greater restraint in the future are recommended.
