Kundalini Yoga is a science which works on the seven chakras, the arcline and aura (eighth chakra.) It works on the flow of energy, and that flow of energy either you sway it or it sways you!
In Kundalini yoga you learn to ride your energy, to experience it and penetrate any given situation to attain a balance.
What is Kundalini? It is your creative potential. You experience it when the energy of the glandular system combines with the energy of the nervous system to create such a sensitivity that the totality of the brain receives signals and integrates them. You become totally and wholly aware, this is the yoga of awareness, your creative potential becomes available to you.
