Definition - What does Anu mean?
Anu is the name of the second of the Inner Tantras within Tantric Buddhism, or the Tantric practice of Hinduism. Anu emphasizes the completion stage of Tantra practice, where creativity, imagination and meditation are engaged. When a practitioner is involved in creating a void where this meditation practice can occur, it results in transformation of the Self. Anu practice also involves releasing or harnessing energy from the chakras to reach bliss and enlightenment.
In Sanskrit, anu has multiple meanings, including “atom, molecule” and “after, alongside.” Within yoga, the term often means “further” or “spiritual union.”
Yogapedia explains Anu
Anu is a philosophy that says freedom or release is achieved by becoming familiar with the insight of the void, which can offer the wisdom to experience or understand the Buddha or deity nature. It is considered a “higher yoga” in which the practitioner meditates on the idea of emptiness, or having the purity of a deity, rather than evolving to connect with a deity through practice. Instead of putting emphasis on the development stage of Tantric practices, it focuses on the completion: experiencing emptiness, bliss and god-like purity throughout practice, similar to Kundalini yoga.
