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 ||
ດັ່ງນັ້ນ ເມື່ອນໍາຄ່າກໍາລັງສາມ (ຄິວບ) ອອກຈາກຈໍານວນຄີກ ຮາກຄິວບຂອງມັນຈະໄດ້ມາຊໍ້າໆ ຕາມວິທີທີ່ກໍານົດ. ແລະເມື່ອຕົວຫານແລະຕົວຖືກຫານ (ຫຼືສ່ວນຂອງມັນ) ຖືກຫັກລ້າງກັນດ້ວຍຕົວຫານຂອງກັນແລະກັນ ຕົວຫານແລະສ່ວນເສດຈະຖືກຫຼຸດລົງຈົນຫາຍໄປສິ້ນເຊີງ.
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).
