Education sans wisdom, wisdom bereft of discrimination, action without discretion, erudition lacking sagacity, power not justified by credentials, statements not based on truth, music wanting in melody, adoration not sustained by devotion, an individual devoid of common sense and character, a student not endowed with humility - these serve no useful purpose. In addition to knowledge derived from the sacred texts, one should earn wisdom through experience. Knowledge without personal experience is futile. (Sathya Sai Vahini, Chapter 21 - “The Inner Inquiry”.)
