ITCH

Generally one wants to be still while meditating, as this facilitates going deeper.  So, if you have an itch, don't scratch; you learn that it eventually goes away.  Same with those thoughts that keep running through our minds while meditating.   Don't scratch--just notice and let them move on through.  (Note:  reacting in some way to them would be the same as scratching them.)

Enjoy the practice!
