Kriyas are cleansing processes. If we want the pranic movement to take place in the right direction and Vata, Pitta and Kapha to become balanced, then the impurities are to be removed. Hence, Kriyas are extremely important. They prepare you for Pranayama that guides you to the awakening of the Kundalini and Meditation.
Pranayama is a very old practice of breathing which is a part of our daily life. Scientific investigations have removed the misconception and established the fact that right breathing has Co2 value, not Oxygen value that is very useful for improving mental faculties. This ultimately leads to a deeper understanding. The Hatha Pradipika goes further and details 8 types of Pranayama: Suryabhedana, Ujjyai, Sitkari, Sitali, Bhastrika, Bhramri, Murccha, Plavini. This explains how practice should be done and the results expected.
