The  Art Of Rock Balancing   Michael Grab is an  artist that has been 'rock balancing' since 2008. Much of
his recent work  has been done around the Boulder, Colorado area. Grab---yes,
that's his  real name---finds the process both spiritual and therapeutic.

Grab  explains:

"The most fundamental element of balancing in a physical  sense is finding some
kind of 'tripod' for the rock to stand on. Every  rock is covered in a variety of tiny
to large indentations that can act as  a tripod for the rock to stand upright, or in
most orientations you can  think of with other rocks. By paying close attention to
the feeling of the  rocks, you will start to feel even the smallest clicks as the notches
of  the rocks in contact are moving over one another.

Parallel to the  physical element of finding tripods, the most fundamental
non-physical  element is harder to explain through words. In a nutshell, I am
referring  to meditation, or finding a zero point or silence within yourself.
Some  balances can apply significant pressure on your mind and your patience.
The  challenge is overcoming any doubt that may arise."
