It is said that there are as many asanas as there are living species: 840,000. That means the muscles and joints can flex, extead - and rotate in several thousand ways. Yogis were in contact with nature and they were searching for natural remedies to combat affliction. In their search, they discovered hundreds of asanas to increase the life-giving force and restore it to its optimum level.
Pranayama, when the breath is wanders the mind is unsteady. But when the breath is calmed, the mind too will be still. Prana is an auto-energizing force. The in breath fans and fuses the two opposing elements of nature-fire and water- so that anew, bioelectrical energy, called prana, is produced. Prana neutralizes the fluctuations of the mind and acts as a spring-board towards emancipation.
