Graha–Ketu–Utpāta Lakṣaṇas: Solar/Lunar Omens, Comets, Eclipses, and Calendar Rules
अर्कभौमदिने षष्ठ्यां नाभ्यंगो वैधृतौ तथा । यः करोति दशम्यां च स्नानमामलकैर्नरः ॥ १४३ ॥
arkabhaumadine ṣaṣṭhyāṃ nābhyaṃgo vaidhṛtau tathā | yaḥ karoti daśamyāṃ ca snānamāmalakairnaraḥ || 143 ||
ஞாயிறு அல்லது செவ்வாயில் வரும் ஷஷ்டி நாளிலும், வைத்ருதி யோகத்திலும் எண்ணெய் அப்யங்கம் செய்யக் கூடாது. ஆனால் தசமி நாளில் ஆமலகத்தால் நீராடும் மனிதன் புனிதப் பயனை அடைகிறான்।

It links inner purity with correct timing: certain tithi–weekday/yoga combinations are treated as ritually unsuitable for indulgent acts like oil-massage, while Daśamī bathing with āmalaka is upheld as a purifying observance that supports dharmic discipline.
Bhakti is supported through niyama (regulated conduct). By observing timing-based restraints and performing purificatory baths, a devotee maintains sāttvika cleanliness and readiness for worship—practical supports for steady devotion.
Jyotiṣa (Vedic astrology): it uses tithi (Ṣaṣṭhī, Daśamī), weekday lords (Sun/Mars), and yoga (Vaidhṛti) to prescribe what actions to avoid or perform for ritual correctness.
