Meditation is the basis of a life of splendid health, untiring energy, unfailing love, and abiding wisdom. It is the very foundation of that deep inner peace for which every one of us longs. No human being can ever be satisfied by money or success or prestige or anything else the world can offer. What we are really searching for is not something that satisfies us temporarily, but a permanent state of joy.
