Procedure for the Guḍa-dhenū (Jaggery-Cow) Gift; Ten Dhenu-dānas; Yearlong Gaṅgā Worship and Darśana
अयने विषुवे पुण्ये व्यतीपातेऽथवा पुनः । युगादौ चैव मन्वादौ चोपरागादिपर्वसु ॥ २८ ॥
ayane viṣuve puṇye vyatīpāte'thavā punaḥ | yugādau caiva manvādau coparāgādiparvasu || 28 ||
At the solstices (ayana), at the equinoxes (viṣuva), on the meritorious Vyatīpāta; likewise at the beginning of a Yuga and at the beginning of a Manvantara; and on sacred junctures such as eclipses and related observances (parva)—these times are especially fit for religious rites.
Narada (teaching within the Uttara-Bhaga’s tirtha/vrata-kāla context)

Secondary Rasa: adbhuta
It highlights “kāla-viśeṣa” (sacred time): solstices, equinoxes, Vyatīpāta, Yuga/Manvantara beginnings, and eclipses are presented as especially potent windows for dharmic acts, multiplying the merit of rites such as snāna, dāna, japa, and vrata.
By directing devotees to spiritually charged parva-times, it supports bhakti-sādhana in practice—encouraging intensified nāma-japa, pūjā, and offerings during auspicious cosmic junctions when devotion is traditionally considered more fruitful.
It reflects Jyotiṣa (Vedāṅga astrology/astronomy) and the calendrical science of parva determination—recognizing ayana, viṣuva, Vyatīpāta yoga, and uparāga (eclipse) as key markers for selecting ritual time.
