Brihat Samhita
ज्यैष्ठ्यां समतीतायां पूर्वाषाढादिसम्प्रवृष्टेन । शुभं अशुभं वा वाच्यं परिमाणं चाम्भसस्तज्ज्ञैः ॥ २३-०१ ॥
Judging from the rain that falls on the days when the Moon passes from the asterism of Pūrvāṣāḍha to that of Mūla in the lunar month of Jyeṣṭha and after the full-moon, an astronomer should predict the agricultural condition of the country as well as the quantity of rainfall in the coming rainy season.
