कालमानं मुहूर्ताङ्गानि च
कौलवे शकुनौ भानुः किंस्तुघ्ने चोर्द्धसंस्थितः ।चतुःपादे तिले नागे सुप्तः क्रांतिं करोति हि ॥ २५९ ॥
In the full Narada Purana (Purva Bhaga) this is chapter 56, verse 259.
At the Kaulava, Shakuni and Kimstughna karana (half of a moon day), the Sun stands upright. At Chatushpada, Tila and Naga, the Sun makes its entry lying asleep.
Simple meaning: The karana at the Sun's entry sets its pose: standing, or lying asleep.
धर्मायुर्वृष्टिषु समं श्रेष्ठं नष्टं फलं क्रमात् ।
The Sun's pose at its entry makes dharma, life and rain average, best or lost.
स्वापोपविष्टास्तिष्ठंतस्ते लोकाः क्षेममाप्नुयुः ।
People matching the Sun's pose fare well. Stars fall into four classes: blind, slow, middle, clear-eyed.
पपीयाद्गणयेद्भानि रोहिण्यादिचतुर्विधम् ।
Count the stars from Rohini in four kinds. The Sun's entry into a fixed sign is Vishnupada.
