AADISHRI ARUN : Man must know where he is going; Light and Sound are both a necessity to know where you are going, and the Sound will be dragging you like anything. You do not know where you are going, so both things should be developed. Sound Principle is the guiding principle. Those who take up only Light, they may be enveloped by Light, but do not know where to go further. The Sound Principle guides there. Both things go hand in hand.
You should listen closely whether any higher Sound is coming, and while listening closely, repetition of the five names should not be done. You will have more Sounds than one, but you have to stick to that of a big bell, a conch, a shell, thunder, drum-beat, a violin (Saarangi) and the flute, which are the higher types of Sounds and leave all the rest.
As regards the Sound of Veena, it somewhat resembles the sound of the instrument which the snake-charmers use to play to catch the snakes. Its tune resembles that of a flute – the difference is that the sound of the flute is shrill compared with that of the Veena – just as the sound of a violin is shrill when compared with that of the flute – and the Sound grows more in volume and thicker and continuous as the soul traverses higher. It is a continuous Sound resembling that of a bagpipe. When you listen to the Sound you are not to follow it to trace out its source of emanation, as in that way it fades out. You should simply keep on listening at your eye-focus with rapt attention. It will draw closer, grow stronger, and ultimately come from above. As for hearing the Sound Current, you will please put in equal time for that soon after your sitting for withdrawal. If, however, this is not possible, you may devote time separately for each practice.
