“The Shaivites envision the pure consciousness of Vast Face as Shiva, and the energy of that consciousness as His consort the Goddess Kali.
The Vedantic philosophy of advaita (non-duality) regards all Name and Form as illusory, and the Brahman (i.e. the Ayn) alone exists.
[Many] Buddhists perform variations of Vast Face meditation practices taught by Gautama Buddha (regarded as the eighth incarnation of Vishnu by Hindus) and other bodhisattvas (souls who reach enlightenment but remain incarnate to teach and help others awaken).
The Buddha practiced jnana yoga (lit. union through direct perception of the Ayn) and taught ashtanga yoga (lit. eight-limbed yoga of concentration and discrimination).
He sat under the Bodhi Tree, renouncing all experiences on all planes of existence. Seeing that all the koshas (Sanskrit words for shells of embodied existence) were empty, he perceived the ultimate Truth of Pure Being in nirvana.
The Vast Face Taoists follow “quietist practices” that lead them to Stillness in the Tao. The principal mood, or bhava, of Vast Face Yoga is called the “shanti bhava” peaceful mood).”
