Inside every human being is a Subtle System of three Channels and seven Chakras. The Chakras- Subtle Energy centers’ control all aspects of our lives; the instinctive biological functions in the lower Chakras; the heart and mind in the upper centers, to the highest spiritual states in the Sahasrara and above. The Atma- Spirit, Consciousness’ in the Left Heart, is our essence, but to know this it is necessary to stop the outward flow of thought and turn within to witness the truth. However it is beautifully arranged, so that when the time is right, the Kundalini- "Pure Spiritual Energy’ dormant in the Sacrum bone, awakens and, as She rises, the attention is pulled inside. Our thoughts subside automatically, and we enter a state of clarity, known as ‘Thoughtless Awareness’. This is the first stage of Self-realization. Another benefit of Sahaja Yoga is that we develop ‘Vibratory Awareness’, the ability to feel the state of our subtle body inside. The condition of the Chakras can be felt on the hands, as colour-coded on the chart of the Subtle System on the front cover. A tingling or pain in one of the fingers indicates a blockage on that Chakra- on the Left Channel if on the left hand, on the Right Channel if on the right hand, and on the Central Channel if on both hands. A breeze on the palms means that the Divine Vibrations are flowing unimpeded.
