Shri Rudram (Sanskrit: श्रीरुद्रम् IAST: śrī-rudram), is a Vedic mantra or chant in homage to Rudra (an epithet of Shiva)

In the principally Shakta theology of Śrī Vidyā "the goddess is supreme, transcending the cosmos which is yet a manifestation of her."[a] She is worshiped in the form of a mystical diagram (Sanskrit: yantra), a central focus and ritual object composed of nine intersecting triangles, called the Shri Yantra or Śrī Cakra .
