Everything as Experience

[anagogy]

So will we lose our awareness when we are infinite again?

You are infinite right now, you are just focusing on the concept of portions rather than wholes.  When you're no longer focusing on portions, the concept of portions is still there within the whole.  Focus on the hole and you see the hole, focus on the whole and you see the whole.  Nothing is lost.  Anything you could possibly cognize, from your memories, to any thought you've ever had has always been a part of infinity, and always will.  The illusion of separation is simply the focusing of the infinite.  

The difference between awareness/spirit and consciousness/mind is similar to the difference between light and color.  Light is general and impersonal, while color is specific and personal.  The color is a reflection against a surface, whereas light can be there without anything to reflect off of.  The mind is the place where the finite "appears" to exist.  Mind/body is the subject/object nexus.  In spirit, subject and object are One.  It is like consciousness that has transcended the relationship -- transcended any sense of separation between two seemingly separate parts.  Understanding the difference between mind, body, and spirit is very powerful key to understanding the nature of the infinite.  The north pole of the magnet is mind, while the south pole of the magnet is matter, and spirit is the integrator between the poles (the magnet itself if you will).  It is the place where opposites are reconciled.  

Spirit is Being, mind is the witness, and the body is what is witnessed.  The spirit looks in the mirror of mind, and sees the inverted reflection of matter (body).  But the accuracy of the reflection is directly proportional to the lack of distortion in the mirror.  Usually our attention is limited to the reflection in the mirror, but occasionally our attention moves to the mirror itself, and finally our attention moves to that which is looking in the mirror -- our true and undistortable beingness.  When attention can be sustained on that aspect, you begin to get glimpses beyond the illusory separation.
