As a river flows, so do your thoughts, never stopping.  They encounter obstacles and take a turn.  At certain points they flow even faster, scurrying to get around the bend.  This constant stream never dries up, propelling you along, along, along until finally you emerge into a larger delta, then merge with the sea, where all thoughts become one.

What happens to the water in the sea?  Do you not remember the diagram shown to you in school?  It evaporates and forms the clouds, only to return to the earth as raindrops and once again flow into the river. 

Thoughts are recycled like raindrops.  Rarely do you have a new one.  Perhaps they are new to you, but recycled from another.  There is only one Mind flowing through all of you.  Ask for the highest thoughts to emanate from your human mind.  Ask for the flow to come from the greatest Source so as to fertilize those around you—renewing all for the greater good.  This is the thought cycle—part of the cycle of life.  As above, so below.
