mehanācca miher dhātor meghatvaṃ vyañjayanti ca
na bhraśyante tato hyāpas tasmādabhrasya vai sthitiḥ
sraṣṭāsau vṛṣṭisargasya dhruveṇādhiṣṭhito raviḥ //

Meghas are called so on account of their sprinkling the landscape (with water.) This expression is formed from the root Miha (to sprinkle.) That which does not throw down water is called Abhra. Hence Abhra is stationary. The sun established by Dhruva is the creator of rain.—35.
