Kundalini is the evolutionary force, at the base of the spine. When awakened, it rises through and vitalizes the chakras, bringing spiritual knowledge, mystical vision, psychic powers, and ultimately, enlightenment."
Gopi Krishna, from Living With Kundalini
"When Kundalini rises through the different chakras ans reaches the highest one - the practitioner enjoys the bliss of Samadhi.
Swami Satchindananda, from Integral Yoga Hata
Kundalini Yoga is the technology, art and science enabling a person to access and utilize his or her own power of creative for the elevation of healing, consciousness and other goals. Shakti meaning force, power or energy is the Hindu concept or personification of God`s female aspect, sometimes referred to as `The Divine Mother`. Shakti represents the active, dynamic principles of feminine power.

There are two kinds of energy. One which is the air energy, which is referred to as chi, or ki, or prana, and then there`s also the Kundalini Shakti energy, which is the energy of cosmic consciousness. This Shakti is considered to lie inactive in the spine`s lower end, and is frequently pictured as a sleeping, coiled serpent. For this reason, it needs to be awakened, either by yogic techniques or spontaneously, and arises to unite with the prana (Universal Energy), empowering the person with awareness out of ordinary sensation and siddhis (powers) away from ordinary ability.

If you have an open third eye, you can actually see the prana particles in the air. You may have noticed sometimes if you look at a bright blue sky, snow, or if you look at the air around a tree, there are lots of tiny swirling comets that seem to wink in and out of existence. Those are prana particles, and the trees make them out of sunlight. That`s why humans feel good in the forest, because we need the chi of trees, and that`s why we need the trees. You may also notice than when the energy is high, they swirl bright and quickly, and when there is less energy they will be less bright and more sluggish in their movements. The prana or Chi energy needs to be directed and affected by human thought. One can change it, direct it and alter it.

Kundalini Shakti is very different, because you cannot tell it what to do. You can ask it nicely, but you cannot control the Shakti energy. The Shakti has its own intelligence that is infinitely wiser than any human being. The Shakti is the God-force, the Goddess-force. It is intelligent.

The Kundalini Shakti comes from God and returns to God. The sudden onset of an increase of energy-flow is often called "awakening" of the Kundalini Shakti. Where does this spiritual power reside in our body? It lies hidden as the dormant energy at the base of the spine. But it has potentiality to wake up and rise through the channels upwards towards the brain. These channels are known as nadis and are three in number. The left is Ida, the right one is Pingala, and the central one is Sushumna. The right and the left join the central one at the base root of the spine, and they cross each other at the level of neck. In most of the persons, at the usual level of human or animal consciousness, the energy currents pass through these two channels, the Ida and the Pingala. As Sushumna remains blocked by dormant residue of energy, like debris obstructing a conduit, our higher or spiritual consciousness remains non-manifest.

The potentiality of perfection is present within every man and woman in the form of very subtle germ or seed. With mediation and instructions from a spiritual Teacher it is possible to activate this latent energy into powerful force that is sure to transcend the limitations of the human mind.
