Geshe Kelsang Gyatso:

Through studying many Buddhist texts we may become a renowned scholar; but if we do not put Buddha’s teachings into practice, our understanding of Buddhism will remain hollow, with no power to solve our own or others’ problems. Expecting intellectual understanding of Buddhist texts alone to solve our problems is like a sick person hoping to cure his or her illness through merely reading medical instructions without actually taking the medicine.
