विश्वगुणादर्श - विदैवज्ञं ग्रामं

विदैवज्ञं ग्रामं विबुधविधुरां भूपतिसभां
    मुखं श्रुत्या जीनं मनुजपतिशून्यं च विषयम् ।
अनाचारन् दारानपहरिकथं काव्यमपि च
    प्रवक्तृत्वापेतं गुरुमपि सुबुद्धिः परिहरेत् ॥

- vishvaguNAdarsha

A wise man will avoid these: a village without a person who understands God (to approach when troubled), a kings court that does not have wise advisors, face of someone who has not studied scriptures, a kingdom that does not have any king, a wife who does not follow Dharma and a poem that is not a story of God (in someway or other) and a teacher who does not teach well.

मनुस्मृति - मेधावी जडवल्लोक आचरेत्

नापृष्टः कस्यचिद्ब्रूयात् न चान्यायेन पृच्छतः ।
जानन्नपि हि मेधावी जडवल्लोक आचरेत् ॥

- मनुस्मृति

- manu smRuti

One must never answer without being asked a question. One must never answer when the question is not posed with correct intentions (illegal, arrogance, etc..). Even after knowing everything, a wise man must act stupid in this world.

- Manu Smriti

किं नु मे स्यादिदं कृत्वा

किं नु मे स्यादिदं कृत्वा किं नु मे स्यादकुर्वतः ।
इति संचित्य मनसा प्राज्ञः कुर्वीत वा नवा ॥

kim nu me syAt idam kRutvA kim nu me syAt akurvataH ।
iti sinchitya manasA prAjnaH kurvIta vA navA ॥

What would happen if I did so? What would happen if I did not do so? A wise man should always think on these lines and finally "do" or "not do". A perfect answer to the eternal question "To do or not to do?"

वेदान्ताचार्य - मूर्ख़ - बुद्धिमान्

भवन्ति बहवो मूर्ख़ाः क्वचिदेको विशुद्धधीः |
त्रासितोऽपि सदा मूर्ख़ैरचलो यस्य बुद्धिमान् ||

- वेदान्ताचार्य

There are many a fools in this world. But there are very few people who can be called wise. Only those who can keep their minds from wavering in spite of attacks from the foolish are the only real wise people.

पंचतंत्र - काकोलूकीय - पण्डितः - सभा

परपरिवादः परिषदि न कथंचित्पण्डितेन वक्तव्यः |
सत्यमपि तन्न वाच्यं यदुक्तमसुखावहं भवति ||

- पंचतंत्र - काकोलूकीय

A wise man knows how to behave in a gathering. He knows well that he must not ridicule/talk harshly to any one (even when they are his opponents). Some times, even the truth must not be told. Especially when it is sure to hurt some one.
