The meaning of Tsa Lung is tsa, which are the subtle channels of the physical body, and lung, meaning wind. Inside each of these physical channels wind must flow. Lu Jong exercises help to open many chakras and subtle channels, but it does not go deep enough. Tsa Lung works with both the body and the breath. It is a technique that combines movements with holding the breath. Because you are holding the breath, the movements can penetrate deeper into the body and open more of the smaller channels, the very subtle chakras. It is only possible to open these small chakras with the breath. Movement alone is not sufficient. Something more subtle, such as the breath, must be used to reach these subtle places.
For the purpose of Tsa Lung practice we believe there are two types of wind: the wisdom wind and the karmic wind. The karmic wind is what blocks the chakras. When the wind is flowing in the channels we call it the wisdom wind. Actually it is the same wind, but if it is blocked we say it is the karmic wind and if it flows we say it is the wisdom wind. When you hold the wind and use special techniques to move it to various chakras in the body, you are able to open all of your subtle chakras. This means that all of your karmic winds are transformed into wisdom winds. We also have both coarse and subtle breath. All speech is coarse breath and the breath itself is the subtle breath.
