Samavritti Pranayama

“Before dealing with the science of Pranayama, it is necessary to understand, what is meant by Prana in yogic science. According to yoga, ‘PRANA’ is a subtle form of energy, that exists for each individual, during his life time. It is neither the inert air that we breathe nor the ATMAN which is the observer of all actions. This PRANA which is separate for each individual, controls the actions of all our faculties, both external and internal, e.g., our power of seeing, hearing, understanding, willing, etc. This PRANA by proper exercise can be strengthened and thus make our senses more acute, give long life, health and strength.

The science of Pranayama deals with the proper methods of exercising the Prana. The exercises consist in lengthening, controlling, etc. of the Prana by regulated breathing. Thus normally, there is regulation during four stages: 1. Inhalation, 2. Retention of air inside, 3. Exhalation, and 4. Retention of air outside. If the durations of these stages are equal, the Pranayama is called SAMAVRITTI…samavritti pranayama leads to general health and well-being.”
