The Self is the Heart...

The Self is the Heart. The Heart is self-luminous.
Light arises from the Heart and reaches the brain, which is
the seat of the mind. The world is seen with the mind, that is, by the
reflected light of the Self. It is perceived with the aid of the mind. When
the mind is illumined it is aware of the world. When it is not itself so
illumined, it is not aware of the world. If the mind is turned in towards
the source of light, objective knowledge ceases and Self alone shines
forth as the Heart.
The moon shines by the reflected light of the sun. When the sun has
set, the moon is useful for revealing objects. When the sun has risen,
no one needs the moon, although the pale disc of the moon is visible
in the sky.
So it is with the mind and the Heart. The mind is useful because of its
reflected light. It is used for seeing objects. When it is turned inwards,
the source of illumination shines forth by itself, and the mind remains
dim and useless like the moon in day-time.
