 may be many obstructions. And each one will do 

 its quota to check the velocity of the stream. And 

 each one will modify and influence the action of 

 the current on the others, so that the swirling 

 waters may even run upstream. And so do 

 gravity and momentum and heat and all other 

 forces change an ever-flowing universal current 

 that is yet the superior, the moving and creating 

 cause of all these manifestations.
