ChU 2.5.1
ऋतुषु पञ्चविधं सामोपासीत । वसन्तो हिङ्कारः । ग्रीष्मः प्रस्तावः । वर्षा उद्गीथः । शरत् प्रतिहारः । हेमन्तो निधनम्
ṛtuṣu pañcavidhaṃ sāmopāsīta | vasanto hiṅkāraḥ | grīṣmaḥ prastāvaḥ | varṣā udgīthaḥ | śarat pratihāraḥ | hemanto nidhanam
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 the seasons. The hinkâra is spring, the prastâva summer (harvest of yava, &c), the udgîtha the rainy season, the pratihâra autumn, the nidhana winter.
Translated by F. Max Müller
