Kali Yantra Key Ring

In many sources Kāli is praised as the highest reality or greatest of all deities. The Nirvana-tantra says the gods Brahma, Vishnu, and Shiva all arise from her like bubbles in the sea, ceaselessly arising and passing away, leaving their original source unchanged. The Niruttara-tantra and the Picchila-tantra declare all of Kāli's mantras to be the greatest and the Yogini-tantra, Kamakhya-tantra and the Niruttara-tantra all proclaim Kāli vidyas (manifestations of Mahadevi, or "divinity itself"). They declare her to be an essence of her own form (svarupa) of the Mahadevi.
