ṛtuṣu pañcavidhaṃ sāmopāsīta vasanto hiṅkāraḥ grīṣmaḥ prastāvaḥ varṣā udgīthaḥ śarat pratihāraḥ hemanto nidhanam

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.
