Bhairava is One with the Transcendant Siva and Nataraja

Bhairava or Rudra, Siva as yogi,

Image of Satguru Sivaya Subramuniyaswami
Among the most intimate, personal forms of communication is the written prayer to the devas or to God. Burned in Agni's sacred fire, it disintegrates in the physical world and quickly re-forms in the astral world.
