The science called Pranayama was originally formulated by the great sage Patanjali and later became the main subject of what is called Raja Yoga, known to the yogis for centuries. It is a path of wisdom that flourished at its highest in the time of Sri Ramakrishna who was the great teacher of two of the most well known “Raja” yoga specialists, namely Swami Vivekananda and Swami Ramana Maharshi.
The basic principles of this science are the awakening of the Kundalini energy as well as control over the technique of conducting that energy to a chosen goal, thereby becoming conscious of the brilliant light that shines as an aura about each chakra, in proportion to the luminousity of the Prana flow.
This process could be explained as follows: when focusing one’s thought on a chosen chakra, that chakra resonates to the vibrations of one’s thought, in attunement with an invisible Prana flow which links the thought to that chakra. At that moment the source of the Kundalini energy, which is dormant at the base of the spine, awakens in accordance with the intensity of the thought, creating an impact on the chakra at which point the initial thought-flow and the Kundalini energy both meet, like a completed circuit joining two wires of opposite polarity.
It is important to understand that when a chosen chakra has been awakened, all other chakras simultaneously react to that process, although their awakening is of a finer degree of intensity. When considering this very important point, it is obvious that great care should be taken in the choice of the chakra that one decides to awaken for a given purpose.
For instance, when practicing the Zikar, the heart chakra is awakening and the consciousness becomes thereby most brilliant, while at the same time the other chakras awaken accordingly, although with lesser intensity.
