Sometimes transliterated as: Jyotistoma, JyotiSToma, Jyotishtoma

Jyotiṣṭoma literally means ‘praise of light’.

Origin of Jyotiṣṭoma

Jyotiṣṭoma is one of the several types of Vedic sacrifices. It belongs to the Soma group. Its standard form is termed as agniṣṭoma.

Stoma means praise. It is a form of chanting the stotras[1] in which the verses are increased by repetition to a certain number. So a stoma is known by a number. For example: trivṛt-stoma which means three fold or nine fold.

Chantings in Jyotiṣṭoma Sacrifice

In the Jyotiṣṭoma sacrifice, the four stomas that are chanted are:

  1. Trivṛt
  2. Pañcadaśa
  3. Saptadaśa
  4. Ekaviṅśa

These are called four jyotis or lights. Hence it is named as Jyotiṣṭoma.


  1. Stotras means Ṛgvedic chants.
