Commentary by TKV Desikachar:

Commentary by S Ramaswami:

“By meditating on the moon, the knowledge of how the stars are arranged is known.
This compares to modern astronomy.

Again some commentators say this takes place on a physical level.
Others say it takes place within the Candra Nāḍi because the light comes in the day and the stars are obscured.”
