ज्योतिषमूलं पञ्चाङ्गं च
आधानपुंससीमंतजातनामान्नभुक्तयः ।चौलङ्कर्ण्ययणं मौंजी क्षुरिकाबंधनं तथा ॥ १० ॥
In the full Narada Purana (Purva Bhaga) this is chapter 54, verse 10.
The rite of conception, the rite for a son, the hair-parting, the birth rite, naming, and first feeding. The first haircut, ear-piercing, the munja-grass girdle rite, and the tying on of the dagger. (Our text is unclear here: one word after ear-piercing.)
Simple meaning: Rites covered: conception, birth, naming, first food, haircut, ear-piercing and the sacred thread.
समावर्तनवैवाहप्रतिष्ठासद्मलक्षणम् ।
More topics: ending study, marriage, house features, journeys, house entry, sudden rain and kinds of acts.
उत्पत्तिलक्षणं चैव सर्वं संक्षेपतो ब्रुवे ।
I will explain all this briefly. Then the places of numbers are named, from one up to a lakh.
स्वाहोरात्रचतुर्भागे दिनरात्रिदले स्मृते ।
A quarter of a planet's day-and-night, corrected, gives half its day and night. Double them for the full lengths.
