Graha–Ketu–Utpāta Lakṣaṇas: Solar/Lunar Omens, Comets, Eclipses, and Calendar Rules
रात्रौ चन्द्र वती राकाप्यमावास्या तथा द्विधा । सिनीवाली चेंदुमती कुहूर्नेंदुमती मता ॥ १४६ ॥
rātrau candra vatī rākāpyamāvāsyā tathā dvidhā | sinīvālī ceṃdumatī kuhūrneṃdumatī matā || 146 ||
రాత్రివేళ చంద్రసహిత తిథి ‘రాకా’ అని ప్రసిద్ధి. అమావాస్య రెండు విధాలు—సినీవాలీ ‘ఇందుమతీ’ (చంద్రయుక్త), కుహూ ‘అనిందుమతీ’ (చంద్రరహిత) అని చెప్పబడింది.
Sanatkumara (in instruction to Narada on technical distinctions of lunar nights/observances)
Vrata: none
Primary Rasa: shanta
Secondary Rasa: none
It emphasizes kāla-śuddhi (purity/precision of sacred time): correctly identifying lunar nights like Rākā and the two forms of Amāvāsyā supports accurate performance of dharma, vows, and rites that underpin spiritual progress.
While not directly teaching bhakti, it supports bhakti-practice indirectly by clarifying when observances and pūjā-based vratas should be timed; disciplined observance (niyama) is presented as an aid to steadiness in devotion.
Jyotiṣa Vedāṅga (Vedic astronomy/astrology): the verse gives a technical distinction within Amāvāsyā—Sinīvālī (with lunar presence) versus Kuhū (without)—useful for calendrical decisions in ritual and vrata timing.
