Brihat Samhita
येषु च भेष्वभिवृष्टं भूयस्तेष्वेव वर्षति प्रायः । यदि नऽप्यऽदिषु वृष्टं सर्वेषु तदा त्वनावृष्टिः ॥ २३-०५ ॥
If there should be rain when the Moon passes through certain asterisms from Pūrvāṣāḍha to Mūla in the lunar month of Jyeṣṭha, then there will also be rain when the Moon passes through the same asterism in the rainy season. If there should be no rain in the month of Jyeṣṭha, there will be no rain in the rainy season.
