Jyotiṣa-śāstra Saṅgraha: Threefold Division, Gaṇita Methods, Muhūrta, and Planetary Reckoning
घनं च विषमादेवं घनमूलं मुर्हुभवेत् । अन्योन्यहारनिहतौ हरांशौ तु समुच्छिदा ॥ २१ ॥
ghanaṃ ca viṣamādevaṃ ghanamūlaṃ murhubhavet | anyonyahāranihatau harāṃśau tu samucchidā || 21 ||
ដូច្នេះ នៅពេលយកអំណាចគូប (ឃន) ចេញពីចំនួនសេស នោះឫសគូបរបស់វា ត្រូវបានរកឃើញម្តងហើយម្តងទៀត តាមវិធីដែលបានកំណត់។ ហើយនៅពេលភាគចែក និងភាគទទួល (ឬផ្នែករបស់វា) ត្រូវបានប៉ះទង្គិចដោយភាគចែករបស់គ្នាទៅវិញទៅមក នោះភាគចែក និងភាគសំណល់ប្រភាគ នឹងត្រូវកាត់បន្ថយរហូតដល់លុបចោលទាំងស្រុង។
Sanatkumara (teaching Narada in an instructional sequence)
Vrata: none
Primary Rasa: shanta
Secondary Rasa: adbhuta
It shows that Moksha-oriented instruction in the Narada Purana also preserves shastric discipline: clarity of method, repeated practice, and precise reduction—habits that support steadiness of mind for dharma and liberation.
Indirectly: the verse models careful, rule-based practice (abhyāsa). The same steadiness and exactness are expected in Vishnu-bhakti—regular repetition and removal of “remainders” like doubt and distraction.
It highlights computational procedure—cube-root extraction and cancellation/reduction of parts—skills aligned with the technical tradition that supports Vedanga disciplines (especially Jyotisha’s arithmetic foundations).
