संस्कारमुहूर्ताः
धनत्रिकोणकेंद्रस्थैः शुभैस्त्र्यायारिगैः परैः ।अभ्यक्ते सन्ध्ययोर्नारे निशि भुक्त्वा न वाहवे ॥ ३४० ॥
In the full Narada Purana (Purva Bhaga) this is chapter 56, verse 340.
Good planets should be in the 2nd, the trikona (luck houses) and the kendra (corner houses). Bad planets should be in the 3rd, 11th and 6th. Do not shave after an oil rub or at the two twilights. Not on Tuesday, at night, after a meal or in battle.
Simple meaning: Shave with good planets well placed. Not after oiling, at twilight, on Tuesday, at night, after eating or in battle.
नोत्कटे भूषिते नैव याने न नवमेऽहि च ।
Do not shave when decked out, on a journey or on the 9th day. Kings shave every 5th day.
कर्तव्यं क्षौरनक्षत्रेऽप्यथ वास्योदये शुभम् ।
Shave on a good star or lagna. It is also allowed at a king's order, a sacrifice or a death.
उद्वाहेऽखिलवारर्क्षतिथिषु क्षौरमिष्टदम् ।
At a wedding shaving is allowed on any day. In lucky rites the razor is offered first.
