If the Moon should appear like a bow, be of disagreeable aspect and of blood color, mankind would suffer from hunger. People living in the direction of the bow string would become powerful and successful in fight. If the Moon’s horn should point downwards, cows and crops would suffer; if it should appear to blaze or smoke, rulers would perish.
If the Moon should appear bright, glossy and of large disc, and if both her horns should be alike, broad and elevated, and if the course of the Moon should lie through the north of the Nāga Vīthi and if she should be within sight of beneíīc planets and free from the influence of malefic ones, mankind would be happy.
पित्र्यमैत्रपुरुहूतविशाखात्वाष्ट्रं एत्य च युनक्ति शशाङ्कः । दक्षिणेन न शुभः शुभकृत् स्याद्यद्युदक्चरति मध्यगतो वा ॥ ४७-१८ ॥
If the course of the Moon should lie to the south of the asterism of Maghā, Anurādhā, Jyeṣṭhā, Viśākhā or Citrā, there would be misery in the land; but if her course should lie through the middle or to the north of the same asterisms, there would be prosperity in the land.
परिघ इति मेघरेखा या तिर्यग्भास्करोदये अस्ते वा । परिधिस्तु प्रतिसूर्यो दण्डस्त्वृजुरिन्द्रचापनिभः ॥ ४७-१९ ॥
The line of clouds across the Sun’s disc at rising or setting is known as Parigha; Paridhi is also known as Pratisūrya or parhelion, and Daṇḍa is an appearance of the shape of a straight rainbow.
