I meditate regularly as part of my daily routine. It gets the energy flowing, my mind clear, I feel calm and relaxed during and after. Meditation is a very powerful practice. Meditation is not concentration. It is de-concentration.
To do any work, you need concentration but to relax and expand you don’t need concentration. Relaxation is the mother of concentration and so if you relax well, you are able to concentrate better. Isn’t that so?
