When you get to know the chakras you will discover that they function as senses in the psychic dimensions, as for instance eyes, ears and also the voice function in the physical dimension. You learn a lot on the course but not all learning takes place in the meditation hall. Your body must be able to transform the energy you acquire from the exercises. After all, you have not come on a hotel holiday, but on a retreat with people who want to work with themselves. And what you want from it is to be better able to deal with the tasks and challenges awaiting you at home.
Activity creates energy and drive.
When one is active, then one is stable. Stability can only be achieved through action. When happiness is achieved one is active. Somebody who cannot find happiness is not active. Many have discovered this secret on our courses.
