meditate on this:

The shape and form of the Om symbol is also representative of the Infinite. In the figure below, you will note that each curve represents the three states of an individual's consciousness; the waking, the unconscious, and the dream states. The dot and semicircle also have significance and represent the Absolute and Maya, respectively:

Lover curve: this curve represents the waking state.

Upper curve: this curve represents deep sleep or the unconscious.

Right curve: this curve represents the dream state (which lies between waking and deep sleep.)

The dot represents the Absolute state of consciousness which illuminates all other states of consciousness.

The semicircle represents Maya (or the veil of the world.) Itseparates the Absolute from the other three curves.

This everpresent OM (or AUM), is the pulse of the universe and the source of our whole being. When we learn to tap into this primordial sound, it becomes a replenishing source of energy.  (unknown credit)
