वर्षति हास्मै वर्षयति ह य एतदेवं विद्वान्वृष्टौ पञ्चविधंसामोपास्ते ॥ २.३.२ ॥
॥ इति तृतीयः खण्डः ॥varṣati hāsmai varṣayati ha ya etadevaṃ vidvānvṛṣṭau pañcavidhaṃsāmopāste || 2.3.2 ||
|| iti tṛtīyaḥ khaṇḍaḥ ||2. When the rain stops, that is the nidhana. If a person performs the fivefold Sāma worship, keeping all this in mind, clouds favour him with rain as he likes when the rain is due, and they may do him this favour even when rain is not due.
Word-for-word explanation:
Udgṛhṇāti tat nidhanam, the end of the rainfall is the nidhana [literally, ‘the end’]; varṣati, it pours; ha asmai, for him [i.e., for the worshipper]; varṣayati, he causes rain to fall; ha yaḥ etat evam vidvān, he who, knowing all this as such; vṛṣṭau, in the rain; pañcavidham sāma upāste, performs the fivefold Sāma worship. Iti tṛtīyaḥ khaṇḍaḥ, here ends the third section.
