In the full Narada Purana (Purva Bhaga) this is chapter 56, verse 392.
For twice-born men who have returned from the teacher's house with a calm mind: in Chitra, the Uttaras, Punarvasu, Pushya, Revati, Shravana, Anuradha and Rohini.
Simple meaning: For men back from the teacher's house, good stars are Chitra, the Uttaras, Punarvasu, Pushya, Revati, Shravana, Anuradha and Rohini.
धृम्रगर्द्दभयोर्नैव व्रणं श्रेयोंत्यभागगम् ।
Dhuma and the ass mean no flaw in the blade. Next come the rules for the return-home rite.
भेष्वर्केंदुज्ञेज्यशुक्रवारलग्नांशकेषु च ।
Use those stars and the Sun, Moon, Mercury, Jupiter or Venus days. Avoid the 1st, 8th, empty days and new moon.
हित्वान्यदिवसे कार्यं समावर्तनमुंडनम् ।
Do the return-home rite and head-shaving on another day. The householder stage is the best of all.
