Hevajra, also known as "The Lord of the Dance," is a tantric deity in Tibetan Buddhism. He is considered a yidam, a meditational deity, which practitioners can visualize and connect with in order to achieve spiritual advancement and attain enlightenment. Hevajra is typically depicted as a blue-skinned man with two faces and four arms. He is shown holding a vajra (a ritual object symbolizing indestructibility) and a bell in his right and left hands, respectively. He is often shown standing on a prostrate figure, symbolizing his subjugation of the forces of evil. He is also depicted wearing a crown of skulls, symbolizing the transformation of negative emotions into wisdom. Hevajra is considered a powerful and fierce deity, associated with the attainment of the highest tantra, the Anuttarayoga tantra. His practice is said to be highly secret and only initiated into those deemed ready by their teachers. The Hevajra practice is said to be a powerful way to achieve spiritual advancement and attain enlightenment and to attain the ultimate level of awareness. Hevajra is also considered a key teaching in Tibetan Buddhism, and it is believed to reveal the secrets of the universe and the ultimate nature of reality. The Hevajra practice is said to be highly effective in removing obstacles, pacifying conflicts, and destroying negative influences. His mantra, "Om Hevajra Hum," is also a popular one to recite for protection and to invoke the power of the Buddha.
