Kundalini yoga is the yoga of transmutation. The principles are simple. At the base of the spine there's an access point that leads into another world, another plane of attention, another dimension. It's possible to access the energy through that secret doorway, that lowest chakra, and bring that energy and power up through yourself into your being. And as you bring it into your being, it will spread and radiate throughout your entire body.

There is a particular path that the kundalini follows -- the shushumna. The shushumna, as I mentioned before, is an astral nerve tube. It's the central nerve tube. There are two others, the ida and the pingala, on either side of it. In most persons, the shushumna is closed. It's a highway that's been shut down. The continuous energy flow that gives us life, that sustains the subtle physical body, takes place in the ida and the pingala.

Just as the blood is constantly flowing through your veins through capillaries -- bringing oxygen to the cells, moving nutrients and wastes around -- so the kundalini energy is constantly flowing through our subtle physical body, our etheric body. It sustains it, heals it. Without that energy, the subtle body grows ill, gets injured or it dies. And when it dies, the physical body dies. We are completely dependent upon the subtle physical body in this world.

The more energy that we have in the subtle physical body, the higher our psychic receptivity is. So kundalini yoga is, in many ways, the study of energy -- its management, its flow, its highs and its lows. But specifically, kundalini is a flow of power. And when we diagram it, we say that it runs from the base of the spine up to the top of the head.
