ChU 2.3.1
वृष्टौ पञ्चविधं सामोपासीत । पुरोवातो हिङ्कारः । मेघो जायते स प्रस्तावः । वर्षति स उद्गीथः । विद्योतते स्तनयति स प्रतिहारः
vṛṣṭau pañcavidhaṃ sāmopāsīta | purovāto hiṅkāraḥ | megho jāyate sa prastāvaḥ | varṣati sa udgīthaḥ | vidyotate stanayati sa pratihāraḥ
Devanagari rendered by HREEM from the edition's roman (IAST) text; the IAST is the edition's own.
Let a man meditate on the fivefold Sâman as rain. The hinkâra is wind (that brings the rain); the prastâva is, 'the cloud is come'; the udgîtha is, 'it rains;' the pratihâra, 'it flashes, it thunders;'
