Many are familiar with the three faces of Siva, called Trimurthi, where He is depicted as Creator, Preserver and Dissolutioner (Yes, it’s in the Fictionary.)
Fewer know the Five Faces of Sadasiva, also called Pancha Brahma. It is a mysterious, profound depiction of the Divine One, which the monks are preparing a major article in Hinduism Today for Twenty-Eleven. The faces are named Isana, Tatpurusha, Agora, Vamadeva and Sadyojata.
This form of Siva adds two faces to the better-known Trimurthi, and two cosmic powers or potencies: Concealing Grace and Revealing Grace. These five faces are often seen on lingams, with four facing the cardinal directions and the fifth facing upward.
These five faces and powers are central to the Agamas’ understanding of the cosmos, a hidden key to worship and puja, and our sculptors in India are just finishing making five of them in metal, to adorn the five niches surrounding the Iraivan sanctum. Here is the architectís drawing of Vamadeva, and the resulting metal murthi.
Bodhinatha's Latest Upadeshas: "The Difference in Practice of Theism and Monism" (September 3, 2014)
During a puja we're in Theism, to receive the blessings of the Deity. After a puja we can go within our self in meditation, giving up the idea of an external Deity, Monism. Monistic Theism: Advaita Ishvaravada. Advaita means the Monism; Ishvara means the Theism.
In Shum we use two words that relate to that: shumif and dimfi. First, perfect your Theism. Then become a monist. That's called Saiva Siddhanta; one leads to the other.
