Lalita is a form of the Goddess, also called the Red Goddess. The thousand names are recited in the Lalita Sahasranama. The Shri Yantra is her diagram.
Within the International Nath Order she is a form of Shakti and of the Cosmic Spirit, not a creed. Mahendranath names her in Twilight Yoga II and in Levogyrate Tantra. She is not Devi as the suffix given to an initiated woman. She is not Kali. The yantra is the machine; this page names the form. It does not teach the thousand names or the nine circuits.
