Jyotiṣa-śāstra Saṅgraha: Threefold Division, Gaṇita Methods, Muhūrta, and Planetary Reckoning
तद्गुमज्या त्रिजिवाप्ता तञ्चापं क्रांतिरुच्यते । ग्रहं संशोध्य मंदोञ्चत्तथा शीघ्नाद्विशोध्य च ॥ ९४ ॥
tadgumajyā trijivāptā tañcāpaṃ krāṃtirucyate | grahaṃ saṃśodhya maṃdoñcattathā śīghnādviśodhya ca || 94 ||
त्रिज्या (त्रिजिवा) यांसह मिळालेल्या ‘गुमज्या’पासून जो चाप (धनु) मिळतो, त्यास ग्रहाची ‘क्रांती’ म्हणतात. नंतर ग्रहस्थिती शुद्ध करून मंदोच्चाचा संस्कार तसेच शीघ्राचा संस्कारही करावा।
Sanatkumara (teaching Narada technical computation within the broader Moksha-Dharma discourse)
Vrata: none
Primary Rasa: shanta
Secondary Rasa: adbhuta
It frames Jyotiṣa as a disciplined, corrective science—refining perception through calculation—supporting dharma by enabling accurate timing and understanding of cosmic order (ṛta).
Indirectly: by teaching precise calendrical and planetary corrections, it underpins proper observance of vows, fasts, and worship timings—practices that nourish steady Viṣṇu-bhakti in daily life.
Vedāṅga Jyotiṣa: converting a sine (jyā) to an arc (cāpa) to obtain krānti (declination), and applying manda-ucca and śīghra corrections for accurate planetary positions (graha-śodhana).
