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 ||
Wenn man durch diese beiden vermindert und vermehrt, erhält man die Rechnung des «Mitte-Sehens»; und die Zeit ist als mit Anfang (mukha) und Ende (anta) zu verstehen. Vom Sonnenmaß an werden die kosmischen Maße als neun und fünfzehn Teile (aṃśa) angegeben.
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.
