संस्कारमुहूर्ताः
स्वोच्चसंस्थोऽपि शीतांशुर्व्रतिनो यदि लग्नगः ।न करोति शिशुं निःस्वं सर्वतः क्षयरोगिणम् ॥ ३७६ ॥
In the full Narada Purana (Purva Bhaga) this is chapter 56, verse 376.
Say the Moon is in its own exaltation sign. Even then, if it is in the boy's lagna (rising sign), it may make him poor. It may bring him a wasting illness in every way.
Simple meaning: Even an exalted Moon in the rising sign can make the boy poor and sickly.
Classical view, not medical advice.
स्फूर्जिते केंद्रगे भानौ व्रतिनां पितृनाशनम् ।
A fierce Sun in a corner house can harm the father. A fault-free rising sign is good.
विना वसंतऋतुना कृष्णपक्षे गलग्रहे ।
Do the rite in spring. Avoid the dark half, bad days, study holidays, bad half-days and the 6th.
त्रयोदश्यादिचत्वारि सप्तम्यादिदिनत्रयम् ।
The 13th to the 1st, the 7th to 9th, and the 4th are the eight bad days.
