Time
Time, like everything else, is One Integrated Reality that has and is duality as its fundamental structure and attribute.
It is always Now and it is always unfolding. Time is simultaneously current and it is the current of its unfolding.
Now is the the centrepoint of time. It is the Living Present created by the Living Relationship of what is called the future and what is called the past.
Now, and all of time has holographic nature that is clearly seen in the fact that all measures of time may be expressed in terms of any one measure of time; for example a day can be measured in seconds such that a day that has 24 hours that each have 60 minutes that each have 60 seconds may be expressed as 24 hours X 60 minutes X 60 seconds or 86,400 seconds. In this way all of it is in every bit of it and every bit of it is in all of it - in other words a hologram.
An excellent model of this Living Relationship is seen in nature as a tree. The trunk is the Now. The roots are the past-future potential and the branches-leaves-seeds are the future-past unfolding. The living inter-action (communication) of the roots and the branches-leaves-seeds creates the Living Reality that is the core - this is the heart or essence of the tree. Thus the extremes are together in the heart. This is space where they meet and from which they flower outward to form the living relationship process called a tree.
In this way all of the tree's growth originates from its heart centre, the Now, that is current as the current moment and it is the current of its unfolding.
To your conscious mind time is linear as in yesterday, today, and tomorrow. To your subconscious mind time is vertical as in eternal and infinite (eternal and infinite do not have any real meaning to your conscious mind). The Living Relationship of your conscious and subconscious mind is their point of intersection that creates and is the timeless present - the Now. Now is the Heart of Time, its substance is Love.
