Jyotiṣa-śāstra Saṅgraha: Threefold Division, Gaṇita Methods, Muhūrta, and Planetary Reckoning
द्विगुणेष्टहृतं रूपं श्रेष्टं प्राग्रूपकं परम् । वर्गयोगांतरे व्येके राश्योर्वर्गोस्त एतयोः ॥ ३३ ॥
dviguṇeṣṭahṛtaṃ rūpaṃ śreṣṭaṃ prāgrūpakaṃ param | vargayogāṃtare vyeke rāśyorvargosta etayoḥ || 33 ||
இஷ்ட ராசியால் வகுத்து கிடைக்கும் ரூபத்தை இருமடங்காக்குவது சிறந்ததும் உயர்ந்ததும் ஆன ‘பிராக்ரூபக’ (முன்-முறை) எனப் போற்றப்படுகிறது. வர்க்க-யோக முறையில் சிலர், இவ்விரு ராசிகளின் வர்க்க விளைவு ஒன்றாகக் கொள்ளப்பட வேண்டும் எனக் கூறுகின்றனர்।

It highlights śāstric discipline: even technical rules are taught with clarity and hierarchy (a “preliminary” and a “best” method), reflecting the Purāṇic ideal that right knowledge (vidyā) supports right living and ultimately aids liberation-minded discernment.
Direct bhakti instruction is not explicit here; instead, it supports bhakti indirectly by emphasizing orderly learning and accurate understanding—qualities praised in Purāṇic tradition for those who seek to serve and contemplate the Supreme with steadiness.
A gaṇita-style computational rule is referenced—doubling, dividing by a chosen quantity, and an operation involving “addition of squares,” indicating a technical, method-based approach akin to Vedāṅga-adjacent scientific instruction.
