लग्नाशयसमानांगोबालिखेटंसमोपि वा ।चंद्रनंदांशवद्वर्णः शीर्षाद्यंगविभागयुक् ॥ ९१ ॥
In the full Narada Purana (Purva Bhaga) this is chapter 55, verse 91.
The child's body is like the lord of the lagna (rising sign)'s navamsha (one-ninth part of a sign). Or it is like the strongest planet. The colour is like the lord of the Moon's navamsha. The body parts are shared out from the head down.
Simple meaning: The child's looks follow the rising sign's part or the strongest planet. Skin colour follows the Moon's part.
शीर्षकं दक्श्रवे नासा कपोलहनवो मुखम् ।
A list of body parts from the head down, read by thirds of the rising sign.
शिश्नापाते च वृषणौ जघने जानुनी तथा ।
More body parts are listed, read on both sides of the body by thirds of the rising sign.
पापयुक्ते व्रणस्तस्मिन्नंगे लक्ष्म च तद्युते ।
A wound or mark on that body part is inborn or comes later depending on the planet's place.
