Pranayama is the conscious and deliberate control and regulation of the breath (Prana means breath, ayam means to control, to regulate). With each breath we absorb not only oxygen, but also Prana. Prana is cosmic energy, the power in the Universe that creates, preserves and changes.
“Self-Inquiry Meditation” is a fundamental aspect of the “Yoga in Daily Life” system. The practice of the Asanas and Pranayamas are progressively developed throughout this system and in the same way, the concentration and meditation practices are also developed step-by-step.
Hatha means willpower, and here it refers to disciplined practice and behaviour using willpower and energy. Hatha Yoga is the path of practice and purification - internal, as well as external. It is, therefore, an additional Yoga path to the four traditional paths. Regular practice of these exercises requires willpower and discipline and that is why this path is called Hatha Yoga.
