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.
To harmonize the two main energies ida and pingala that exist in the body and often compared to the positive and negative forces involved in electricity, we learn to practise exercises known in yoga teaching under the term pranayama. One of the main such exercises is called Nadis Shodana, one of the most famous exercises known to all who choose to take up Yoga practice. It regulates the flow of our breath equally through the right and left nostrils. This ensures that the brain itself directly benefits from both the pranic energies before it subsequently conveyed to the lungs. You will derive real mental health benefit from practising this exercise.
It is simple in principle but requires patience and an unhurried interval of time. It is recommended that you seek personal guidance from a yoga teacher to clarify the technique used in this classic exercise to assist you in keeping the mind calm, clear and capable.
It will help you achieve equilibrium, the most important requirement in our psychological and general well being.
