While the Kama Sutra is often associated with Tantra and Indian spirituality, it is not a part of the core teachings of Tantra. The Kama Sutra is a text on the art of love and sexual pleasure, written by the Indian sage Vatsyayana in the 2nd century CE. It is a standalone text and not a part of any specific spiritual tradition or lineage.
That being said, the Kama Sutra does contain some references to Tantra and Tantra-related practices, such as the use of mantras, meditation, and other techniques for enhancing sexual pleasure and spiritual awareness. It also shares some similarities with Tantra in its approach to sexuality and the importance placed on sexual energy and its role in spiritual transformation.
However, it is important to distinguish between the Kama Sutra and Tantra as separate traditions. While there may be some overlap and similarities between the two, they are distinct and separate systems of thought and practice.
