कर्णश्रवेऽनिले रात्रौ दिवा पांसुसमूहने । एतौ वर्षास्वनध्यायावध्यायज्ञाः प्रचक्षते ॥ १०२ ॥
sanskrit
Those who know the (rules of) recitation declare that in the rainy season the Veda-study must be stopped on these two (occasions), when the wind is audible at night, and when it whirls up the dust in the day-time.
