All teachings of philosophic value encourage the attainment of a state of balance and harmony. In yoga it is recognized as the state of equilibrium following flux, movement and change. This applies to the relaxed state of consciousness that follows all activity, including dynamic physical exercise programmes. Controlled breathing rhythms and habits are found to effectively assist us.
The techniques used are practised with the knowledge of the inter-relationship of breathing and thought. A simple example of this is when we breathe slowly and deeply and feel consequently more relaxed and peaceful. When we inhale at a quicker rate it has the opposite effect and helps stimulate our energies towards activity.
