While you meditate, past and future do not exist. Most people believe that some material object will bring this happiness such as money, a perfect spouse, a dream job, a new car, a big expensive house, but in reality, the list that would make you completely happy is never ending. As long as you think that happiness will come from something outside yourself, you will never be happy and never feel healthy. Happiness, the blissful state, comes from within yourself. Anyone who believes otherwise is like a person wandering around on a deserted island, constantly disappointed by mirages of transportation and a telephone.
Worldly happiness is equally elusive, always just beyond our grasp.
Meditation through yoga provides a lasting spiritual rest, which must be experienced to be understood. Once you can meditate, even the amount of sleep you need can be reduced to as little as three hours per night, and you will still feel more rested and peaceful than before. By reducing heart rate and consumption of oxygen, meditation greatly reduces stress levels which inturn increases health benefits. It seems that each part of the body, even down to the individual cells is taught to relax and rejuvenate. Meditation helps to prolong the body's period of growth and cell production, and reduces the decaying process.
