Advaita Vedanta is a school of Hindu philosophy and is not generally considered a part of Indian Tantra. While Advaita Vedanta and Tantra share some similarities, such as a focus on spiritual realization and the use of meditation and other practices to achieve that goal, they also have significant differences in their approaches and teachings.
Advaita Vedanta emphasizes the nondual nature of reality and the ultimate identity of the individual soul (atman) with the supreme reality (brahman), and its teachings are based primarily on the Upanishads, the Bhagavad Gita, and the Brahma Sutras. In contrast, Tantra emphasizes the use of various practices, including the use of mantras, yantras, and rituals, to achieve spiritual transformation and realization.
While there may be some overlap between Advaita Vedanta and Tantra in terms of their teachings and practices, they are generally considered distinct and separate traditions within Indian spirituality.
