All followers of Raja Yoga must first be devotees. Only intense love of the soul and of all that knowledge of the soul entails will carry the aspirant with sufficient steadiness toward his goal. The objective in view - union with the soul, and consequently with the Oversoul and with all souls - must be justly appraised; the reasons for its achievement correctly judged, and the results to be gained most earnestly desired (or loved) before the aspirant will make that sufficiently strong effort which will give him his hold upon the modifications of the mind and consequently upon his [28] entire lower nature. When this appreciation is true enough and his ability to go forward with the work of subjugation and control is without intermission, then the time will come when the student will know consciously and increasingly what is the meaning of restraint of the modifications.
