The real meaning of fasting lies in spiritual exercise. The Sanskrit name of yoga on fasting is UPAVASA, which means to keep the closest to the supreme consciousness, that is, to integrate the individual mind into the wave of supreme consciousness. Because you don't need too much energy to digest food when you are fasting, your brain will become extremely clear. If you guide these energies with appropriate spiritual methods, your mind will be raised to the highest level of consciousness. Fasting is not only the purpose of spiritual practice, but also one of the oldest natural therapies and methods used to control the mind and appetite.
