Penetration

Nothing has greater power of penetration that the sun's rays.
Similarly, nothing has greater power of penetration
than man's thought when it is identified with sunlight.
Thought can penetrate anything and everything;
nothing can stand in its way.
Nothing can stand in its way, that is, if it is intense;
but if it is the feeble, flickering flame of a candle, or a mere flash in the pan,
all kinds of obstacles will vanquish it.

Only those who are capable of penetrating things
have the power to change them.
For example, it you want to heal a diseased organ,
you have to concentrate on it
and send rays of light into every cell, every atom and electron.
You have to flood it with vibrations of light, health and goodness.
