“Keep
your mind at the point between the eyebrows,
where the spiritual eye is located. If you
concentrate long and deeply through the spiritual
eye, you will get the right answer to any
problem. Meditate until the light of God appears.
Never go to sleep until you have contacted
the divine joyful vibration of God. Always
remain in the mental sphere of happiness born
of meditation, no matter what happens. Concentrate
upon the great peace within, and you will
see the shadow of world limitations melting
away. Out of it you will see that behind this
motion picture of delusion there is a world
eternal–the infinite astral world.”
