Jyotiṣa-śāstra Saṅgraha: Threefold Division, Gaṇita Methods, Muhūrta, and Planetary Reckoning
सेष्वशोनाः सितं तिथ्यो बलन्नाशोन्नतं विधोः । श्रृङ्गमन्यत्र उद्वाच्यं बलनांगुललेखनात् ॥ १६९ ॥
seṣvaśonāḥ sitaṃ tithyo balannāśonnataṃ vidhoḥ | śrṛṅgamanyatra udvācyaṃ balanāṃgulalekhanāt || 169 ||
Pada hari-hari yang selebihnya, bahagian-bahagian bulan hendaklah difahami sebagai “putih/cerah” menurut tithi; naik-turun (membesar-mengecil) Bulan disimpulkan daripada terbit dan tenggelamnya. Arah “tanduk” (hujung sabit) pula dinyatakan berbeza di tempat lain, berdasarkan tanda yang dibuat oleh jari—yakni ukuran dan pemerhatian amali.

It emphasizes that Dharma and vrata-observance should be grounded in accurate knowledge of time (kāla)—using tithi and lunar condition—so that spiritual practices are performed with clarity and correctness.
Bhakti is supported by disciplined observance; the verse highlights the practical side of devotion—keeping vows and worship on the proper tithis—so that devotional acts align with scriptural timing rather than guesswork.
Vedāṅga Jyotiṣa: reading tithi-related lunar phases (waxing/waning) and using simple observational measures (like finger-marking) to describe the Moon’s crescent orientation for calendrical/ritual purposes.
