To solve a problem, to learn a lesson, a lot of concentration and attention is needed, everyone knows that—an intellectual attention and concentration. But concentration is not only an intellectual thing, it may be found in all the activities of the being, including bodily activities. The control over the nerves should be such as would allow you a complete concentration on what you are doing and, through the very intensity of your concentration, you acquire an immediate response to external touches. To attain this concentration you need a conscious control of the energies.
Are you conscious of the energies you receive and those you spend?
One is more or less conscious of the energy one spends, especially when one wastes it too much! It is a question here of the constant exchange between receiving and spending! Before the age of reason, little children receive a lot of energy and they spend it lavishly, without thinking, and this allows them to play for hours together without getting tired. But gradually, as thought develops, one begins to measure and calculate the energy spent—usually this is futile, for unless you have the knowledge of the process of receiving energy, it is better to spend freely what you get than let it stagnate within you.
