Why do you dig in your heels? 
Because you are quite earthbound when you do so.  It is the human side of you that has such set
ideas that you take your very human heels and dig them quite firmly into the
very earthly ground and stand that ground. 
And what does this gain you?  A
sense of separation and righteousness. 
What happens when you look down upon your humanness from the viewpoint
of yourself as spirit?  Why, you become
so light that you rise up and float right out of those firmly planted
feet.  From there you not only can
relieve the tension of being so firmly rooted in your position, but you may
even smile to see all the others rooted in place.  And then you may even laugh to see how
interconnected you all are at the roots beneath all the surface
differences.  But of course you cannot
see this until you rise above.
