What is Kundalini Yoga?
Kundalini Yoga’s origins come from the beginning of time and seem to have roots in the wisdom traditions of every culture in which a spark of consciousness has been lit. It gives the tools, technology, the sadhana, the personal discipline, to awaken awareness.
               Kundalini Yoga is a science which works on the seven chakras, the arc line and the aura. It works directly on the total energy, and that flow of energy has one simple way: either YOU sway it or IT sways you.
               Either you are above the energy riding it or you go below the energy and it rides you. That is where Kundalini Yoga fits in : you will learn to ride your energy, to experience it and penetrate any given situation to attain balance. What is kundalini actually? 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. Then you become totally and wholly aware, and your creative potential becomes available to you.

The power of Kundalini Yoga lies in the actual experience. It goes right into your heart and extends your consciousness so you may have a wider horizon of grace and of knowing the truth. Ultimately you come to understand your existence in relationship to the universe and understand you already are, and this brings you to the practical experience of Infinity. You can then radiate creativity and infinity in all aspects of your daily life.
