संस्कारमुहूर्ताः
नचेन्नवांशके कर्तुरष्टमोदयवर्जिते ।शुद्धेऽष्टमे विधौ लग्ने षष्ठाष्टांत्यविवर्जिते ॥ ३८२ ॥
In the full Narada Purana (Purva Bhaga) this is chapter 56, verse 382.
The navamsha (one-ninth part of a sign) must not be the 8th from the doer's birth sign. Nor must the lagna (rising sign). The 8th house is clean. The Moon is out of the 6th, 8th and 12th from the lagna.
Simple meaning: Avoid a rising sign 8th from the birth sign. Keep the 8th clean. Keep the Moon out of 6, 8, 12.
आयामार्द्धाग्रविस्तारप्रमाणेनैवच्छेदयत् ।
Measure and cut the blade by its parts. A Dhvaja count may help defeat enemies.
धूम्राये मरणं सिंहे जयः शुनि च रोगिता ।
Dhuma may risk life, Simha bring victory, Shva sickness, Vrisha wealth and the ass sorrow.
गजायेऽत्यंतसंप्रीतिध्वांक्षे वित्तविनाशनम् ।
Gaja brings love and the crow may bring loss of wealth. Measure a sword or dagger by your own finger-width.
