The Chakra Meditation method Bhuta Shuddhi works directly with attention on the chakras, balancing the subtle forces of the five elements through the use of the bija (seed) mantras of the chakras.
Before doing the Chakra Meditation - Bhuta Shuddhi practice itself, it is useful to do some some stretches or hatha asanas (postures) this helps prepare the mind to be able to focus on the chakras.
Before you attempt anything that is considered as a mystical process, it is very important to stabilize the five fundamental elements within you. These are known as pancha bhutas or maha tatwas in the yogic science. The body, the very earth, the universe, and the cosmos, all are just a play of five elements. The body’s composition is such that most of it is water. Then there is earth, air, fire, and the rest is akash or etheric space.
How these five elements behave within you determines just about everything. Bhuta means element, bhuta shuddhi means to become free from the taint of elements or to cleanse the elements. It means to become free from the physical nature. Most human beings are completely in the grip of their physiological and psychological processes. Our physiology is something that we have accumulated. Likewise, the whole content of our psychological process has been accumulated in the form of impressions.
