Adhyāya 164: Gautama as Guest; Kaśyapa’s Satkāra and the Fourfold Arthagati; Journey to Virūpākṣa
विभ्रमाल्लोकबाह्वानां द्वेष्यैर्वाक्यैरसम्मतै: । कुत्सा संजायते राजॉलल्लोकान प्रेक्ष्याभिशाम्यति
vibhramāl lokabāhyānāṃ dveṣyair vākyair asammataiḥ | kutsā saṃjāyate rājann al lokān prekṣyābhiśāmyati ||
毗湿摩说道：大王啊，若因那些被逐出良善社会的卑劣之人所说的怨毒而不可信之言而心生迷乱，便会滋长挑剔诋毁之习。然一旦得见高贵贤者，此倾向即得安息而消退。

Educational Q&A
Malicious and untrustworthy talk from degraded company breeds a habit of censure, but the sight and association of noble people calms that impulse; therefore one should avoid corrupt influences and seek the company of the good.
In Bhishma’s instruction to the king in the Shanti Parva, he explains how a ruler’s mind can be disturbed by hostile, unreliable counsel from unworthy persons, and how exposure to virtuous people restores calm and right judgment.
