Jyotiṣa-śāstra Saṅgraha: Threefold Division, Gaṇita Methods, Muhūrta, and Planetary Reckoning
तद्देशांतरनाडीभिः पश्चादूने विनिर्दिशेत् । इष्टनाडीगुणा भुक्तिः षष्ट्या भक्ता कलादिकम् ॥ ८८ ॥
taddeśāṃtaranāḍībhiḥ paścādūne vinirdiśet | iṣṭanāḍīguṇā bhuktiḥ ṣaṣṭyā bhaktā kalādikam || 88 ||
Using the nāḍīs that correspond to the difference between places, one should state the later time as diminished accordingly. The ‘bhukti’ is obtained by multiplying by the desired nāḍī-factor; and when divided by sixty, it yields kalā and the other smaller time-units.
Sanatkumara (teaching Narada)
Vrata: none
Primary Rasa: shanta
Secondary Rasa: none
It supports Moksha-Dharma practice by making sacred duties precise—right timing (kāla-śuddhi) strengthens the correctness of vrata, japa, and other observances that aid inner discipline.
Indirectly: it shows that devotion is supported by orderly conduct—devotional rites and daily worship are traditionally aligned with proper time-reckoning, so bhakti is practiced with śāstric accuracy rather than guesswork.
Vedāṅga Jyotiṣa: correcting time based on deśāntara (place-difference) and converting larger units to smaller ones (nāḍī → kalā, etc.) via multiplication and division by sixty.
