Prana creates a field of possibilities where the seed of any idea develops rapidly, where our activities proceed smoothly and bear rich dividends. To develop prana, meditation, pranayama and a calm attitude are key. Freshly-cooked healthy food, pure fresh air and yogic exercise nurture and enhance prana. When prana is in full flow, the person is full of vitality, energy and enthusiasm. Prana is the life-force that flows in all living things. Eating too much, consuming stale food, exercising till you are ready to drop dead, constant arguments, overworking, getting emotionally upset, breathing polluted air, all interfere with the smooth flow of prana. Moderation is the rule.
