You may be engaged in the most active action, for example, in playing basketball, which needs a great deal of movement, and yet not lose the attitude of inner meditation and concentration upon the Divine. And when you get that, you will see that all you do changes its quality; not only will you do it better, but you will do it with an altogether unexpected strength, and at the same time keep your consciousness so high and so pure that nothing will be able to touch you any longer…
Do not fall into the very common error of believing that you must sit in an absolutely quiet corner where nobody passes by, where you are in a classical position and altogether immobile, in order to be able to meditate – it is not true. What is needed is to succeed in meditating under all circumstances, and I call "meditating" not emptying your head but concentrating yourself in a contemplation of the Divine.
