वसन्तो हिङ्कारो ग्रीष्मः प्रस्तावो वर्षा उद्गीथः शरत्प्रतिहारो हेमन्तो निध-नमेतद्वैराजमृतुषु प्रोतम् ॥ १ ॥
In plain words
Spring is the hiṃkāra, summer is the prastāva, the monsoon rains are the udgītha, autumn is the pratihāra, and winter is the nidhana. Thus the Vairāja sāman is woven across the seasons.
