Desire can be directed according to the personal will. Living life according to basic spiritual principles is your sadhana. Through sadhana you can gain mastery over all the forces of your mind and body. As man leaves his instinctive-intellectual nature and unfolds spiritually, the forces of that nature must be brought under his conscious control. The successful practice of brahmachariya creates a deva-like person.
Desire is life.
It can be channeled according to choice. Brahmachariya is essential to spiritual culture. We hope that you have been able to set aside a half-hour, or at least fifteen minutes a day, for your study of these lessons. If not, don't be discouraged. If nothing more, please try to read a little from your daily lesson each night before you go to sleep.
