Shiva Swarodaya

The state of our body and mind is reflected in the alternation of the swara cycles. If either nadi predominant for too long, it is a sign of warning, that one of the branches of the autonomic nervous system is being over stressed, and only one of the brain hemispheres is being fully utilized. If ida nadi flows for a long time beyond the normal schedule, this signifies some imbalance in the mind. Or if pingla nadi flows beyond schedule, there is some sort of imbalance in the pranic body. When the physical and mental energies are imbalance, the personality is only half developed and sickness of some type is inevitable. In order to correct this situation there must be regular alternation of the swara.

The Shiva Swarodaya advises that for good health the sadhaka and yogi should maximize the flow of ida during the day and the flow of Pingla at night. We should keep in mind that yogi's life is dedicated to sadhana and not household duties. Nevertheless, by adjusting the swara in such a way, the natural tendency of the body to become overheated during the day, and overcool at night is counter balanced with wide reaching effects.

In swara yoga, it has been seen that ida and Pingla operate alternately and that they flow in rhythmic cycle.

Therefore, in order to maintain balance, harmony and equilibrium of body, mind and prana, it is said : if the air is inhaled through the left nostril, it should be expelled again through the right. Then breathing in through the right and retaining, it should be expelled through the left. This particular practice, which is known as nadi shodhana, brings regularity in the whole system and is extremely important in swara yoga for harmonizing the pranic flow. ~ Swami Muktibodhananda.
