Narada Purana (Jyotisha Selections) · by Vyasa
Chapter 6 · Calendar, Muhurta Elements
कालमानं मुहूर्ताङ्गानि च
शुभो जन्मर्क्षतश्चंद्रो द्यूनांगायारिस्वत्रिषु ।यथेष्टांत्यांबुधर्मस्थैविबुधैर्विध्यते न चेत् ॥ २७२ ॥
In the full Narada Purana (Purva Bhaga) this is chapter 56, verse 272.
The Moon is good from the birth sign in the 7th, 1st, 11th, 6th, 'sva' and 3rd. That holds if planets other than Mercury do not block it. They block from 'yathesta', the 12th, the 4th and the 9th. (Our text is unclear here: the 'sva' place and the word 'yathesta'.)
Simple meaning: The Moon is good in several places from the birth sign, unless other planets block it.
त्र्यायारिषु कुजः श्रेष्ठो जन्मना चेन्न विध्यते ।
Mars is good in the 3rd, 11th and 6th, unless planets in the 12th, 5th or 9th block it.
ज्ञः स्वायार्यष्टखायेषु जन्मतश्चेन्न विध्यते ।
Mercury is good in the 2nd, 6th, 8th, 10th and 11th, unless other planets block it.
जन्मराशेर्गुरुः श्रेष्ठः स्वायगोऽध्यस्तगो न चत् ।
Jupiter is good in the 2nd, 5th, 7th and 11th, unless planets in blocking places stop it.
