Wisdom

Buddhism: The mind is very hard to perceive, extremely subtle, flits wherever it lists. Let the wise person guard it; a guarded mind is conducive to happiness (Dhammapada 36).

Christianity: Wisdom is worth more than weapons of war, but a single sin undoes a deal of good (Ecclesiastes 9:18).

Hinduism: Whose mind is not agitated in adversity, which is free from desire, and who is devoid of attachment, fear and anger—such a person is called a sage of steady wisdom (Bhagavad Gita 2, 56)

Islam: There is no greater wealth than wisdom; no greater poverty than ignorance; no greater heritage than culture (Nahjul Balagha, Saying 52)

Jainism: The wise man looks upon life as a mere dew drop which quivers upon the tip of a blade of grass, to be whisked off or blown away by the breeze at any moment (Acarangasutra 5.5)

Sikhism: True learning in the mind is service of mankind (Adi Granth, Asa, M.1)
