Shloka 173
कामद्रुम-रूपकः तथा शरीर-पुर-रूपकः
The Desire-Tree and the Body-as-City Metaphors
न तर्कशास्त्रदग्धाय तथैव पिशुनाय च । जो वेदका विद्वान् न हो
na tarkaśāstra-dagdhāya tathaiva piśunāya ca | yo vedakaḥ vidvān na bhavet, anugata-bhakto na bhavet, doṣa-dṛṣṭi-rahito na bhavet, sarala-svabhāvo na bhavet, ājñākārī na bhavet; tarkaśāstra-nindayā nindayā yasya hṛdayaṃ dagdhaṃ rasa-śūnyaṃ jātaṃ, yaś ca pareṣāṃ piśunatāṃ karoti—tādṛśebhyo ’sya jñānasya upadeśo na yuktaḥ ||
毗耶娑说道：“此教诲不应传授给那种因好争之理辩而使内心被灼烧得枯槁的人，也不应传给诽谤者。若有人并非真正博学，不是虔诚随行之弟子，不离挑剔过失之习，性情不质朴，且不知顺从；又因不断讥评、纠缠于论理之学而使其内在之心焚尽，失却对真理的滋味，同时还沉溺于背后中伤——那么，将此知识教与此人，实非所宜。”
व्यास उवाच
Educational Q&A
Sacred or liberating knowledge should be given only to a fit recipient: one who is genuinely learned, devoted, straightforward, obedient, and free from habitual fault-finding and slander. Mere argumentative cleverness that dries up the heart is treated as disqualifying.
In the didactic setting of Śānti Parva, Vyāsa lays down criteria for transmitting higher instruction, warning that people consumed by polemical logic and backbiting are not suitable students for this teaching.
