Jain Tantric worship aims to control other people or counter evil influences. Tantric rituals try to placate the aggressive side of a deity’s nature, encouraging the divinity to behave benevolently. If not worshipped correctly, the vengeful deity may cause harm. The devotee invokes the deity under his or her various names, places images of the deity on yantras – mystical diagrams – and meditates, repeating mantras.
