Narada Purana (Jyotisha Selections) · by Vyasa
Chapter 11 · Rain, Kurma Chakra, Utpata
वृष्टिः कूर्मचक्रम् उत्पाताश्च
संध्ययोः सस्यवृद्धिः स्यात्सर्वसंपन्नृणान्निशि ।स्तोकवृष्टिरनर्घः स्यादवृष्टिः सस्यसंपदः ॥ ७२८ ॥
In the full Narada Purana (Purva Bhaga) this is chapter 56, verse 728.
Rain at the two twilights makes crops grow. At night it brings all wealth to people. Little rain makes grain costly. With no rain, the verse names a wealth of crops. (Our text is unclear here: how no rain goes with good crops.)
Simple meaning: Rain at twilight helps crops and at night brings wealth. Little rain makes grain costly.
आर्द्रोदयेग्रभिन्ना चेद्भवेदिति न संशयः ।
The Moon, Jupiter, Mercury or Venus in a corner house ends the plague on crops.
पूर्वाषाढां गतो भानुर्जीमूतैः परिवेष्टितः ।
The Sun in Purva Ashadha, wrapped in clouds, brings daily rain from Ardra to Moola.
वृष्टिश्चेत्पौष्णभें तस्माद्दशर्क्षेषु न वर्षति ।
Rain in Revati means no rain for the next ten stars.
