Whatever the character of the experience you have, you must give no room to fear; you must keep an unshaken confidence and feel that whatever happens is the thing that had to happen. Once you have chosen the path, you must boldly accept all the consequences of your choice. But if you choose and then draw back and choose again and again draw back, always wavering, always doubting, always fearful, you create a disharmony in your being, which not only retards your progress, but can be the origin of all kinds of disturbance in the mind and vital being and discomfort and disease in the body.
