Commentary
Hariharānanda Bhāratī’s Sanskrit commentary, translated
"Candrārkau" and the rest. Then, making the Moon and the Sun witnesses, he should stir the aśvattha leaves on which the names of the nāgas are written and draw out one aśvattha leaf with a nāga's name written on it. Whatever nāga comes up there, that nāga he should make the guardian of the water.
