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 ||
ઇષ્ટ રાશિથી ભાગ આપીને મળેલા રૂપને દ્વિગુણ કરવું—આને શ્રેષ્ઠ અને પરમ ‘પ્રાગ્રૂપક’ (પૂર્વરૂપ) કહેવાયું છે. વર્ગ-યોગ પદ્ધતિમાં કેટલાક કહે છે કે આ બે રાશિઓનો વર્ગફળ સંયુક્ત રીતે માનવો।

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.
