Jyotiṣa-śāstra Saṅgraha: Threefold Division, Gaṇita Methods, Muhūrta, and Planetary Reckoning
ताभ्यां हीनयुतो मध्यदर्शः कालौ मुखांतगौ । अर्काद्यूना विश्व ईशा नवपंचदशांशकाः ॥ १६५ ॥
tābhyāṃ hīnayuto madhyadarśaḥ kālau mukhāṃtagau | arkādyūnā viśva īśā navapaṃcadaśāṃśakāḥ || 165 ||
Quand, par ces deux unités, on retranche et l’on ajoute, on obtient le calcul dit « voir le milieu »; et le temps doit être compris comme ayant un commencement (mukha) et une fin (anta). À partir du Soleil, les mesures cosmiques sont énoncées comme neuf et quinze parts (aṃśa).
Sanatkumara (teaching Narada in a technical/disciplinary passage)
Vrata: none
Primary Rasa: shanta
Secondary Rasa: none
It frames kāla (time) as a measurable, ordered principle with a beginning and end, supporting disciplined understanding of the cosmos—an aid to viveka (discernment) that underlies Moksha-Dharma.
Indirectly: by teaching accurate reckoning of kāla and cosmic order (often used to time vrata and worship), it supports orderly devotional practice even though the verse itself is technical rather than emotive bhakti.
Vedāṅga Jyotiṣa-style computation: using addition/subtraction to derive a ‘middle’ (madhya) measure and describing divisions (aṃśas) anchored ‘from the Sun onward’ for time/cosmic reckoning.
