Ārjava, Satya, and the Virocana–Sudhanvan Exemplum
Udyoga-parva 35
अकस्मादेव कुप्यन्ति प्रसीदन्त्यनिमित्तत: । शीलमेतदसाधूनाम श्र पारिप्लवं यथा,दुष्ट पुरुषोंका स्वभाव मेघके समान चंचल होता है, वे सहसा क्रोध कर बैठते हैं और अकारण ही प्रसन्न हो जाते हैं
akasmād eva kupyanti prasīdanty animittataḥ | śīlam etad asādhūnām yathā pariplavaṃ ghanaḥ ||
毗度罗说：恶人天性反复，如飘移之云。其怒无端骤起，其喜亦无故忽生。此等不定，正是不义之徒的标记，使其在谋议与行事上皆不可托付。

In Vidura’s counsel during the tense pre-war negotiations of the Udyoga Parva, he warns about the temperament of wicked people, using the image of a drifting cloud to describe their unpredictable reactions.
