Graha–Ketu–Utpāta Lakṣaṇas: Solar/Lunar Omens, Comets, Eclipses, and Calendar Rules
शुभाशुभे कर्मणि च प्रशस्तौ भवतः सदा । क्रमात्तिथीनां ब्रह्माग्नी विरिंचिविष्णुशैलजाः ॥ १३३ ॥
śubhāśubhe karmaṇi ca praśastau bhavataḥ sadā | kramāttithīnāṃ brahmāgnī viriṃciviṣṇuśailajāḥ || 133 ||
Tanto nos ritos auspiciosos quanto nos inauspiciosos, vós dois sois sempre declarados dignos de louvor. Na sequência ordenada dos tithis (dias lunares), as potências regentes são Brahmā e Agni, e também Virinci, Viṣṇu e Śailajā (Pārvatī).
Sanatkumara (in instruction to Narada, within Moksha-Dharma/ritual-timing context)
Vrata: none
Primary Rasa: shanta
Secondary Rasa: bhakti
It links dharmic action to sacred time: even when rites concern favorable or unfavorable outcomes, their correctness depends on tithi-order and the deities presiding over those lunar days.
By naming Viṣṇu among the presiding powers of tithis, the verse implies that devotion is practiced not only through sentiment but also through disciplined observance of time-sanctified worship and vows.
It reflects Jyotiṣa-Vedāṅga usage: the sequencing of tithis and their associated deities, applied to deciding timing and propriety of rituals and vratas.
