The hinkâra is fire, the prastâva air, the udgîtha the sun, the pratihâra the stars, the nidhana the moon. That is the Râgana Sâman, as interwoven in the deities.

In plain words: The five parts of the chant are matched to the gods of nature: fire, air, the sun, the stars and the moon. This is the Râgana chant found in the gods.
