Shanti-dhara (शांतिधारा) means the "stream (dhara) of peace (shanti)." In Jain practice it refers to a ritual where a continuous flow of water is poured over a Tirthankar’s idol or image while peace-oriented mantras or prayers are recited. The idea is to bless the place, remove inner and outer obstacles, and invite calm and auspiciousness for the devotee and for all beings.

• Common practice: water from a kalash is coursed over the idol as a symbolic washing away of impurities and karmas, accompanied by the Shantidhara mantras. A typical phrasing used in this rite is Om Hreem Shantidharaya Swaha. The ritual can be performed during abhishek (anointing) ceremonies and is especially common in temple rites and during festivals.
