And the heart is not the ultimate, you have to move
even deeper than the heart. And then you come to your
navel – what the Japanese call
'hara'. These
are the three centers: hara – two inches
below the navel; heart, and head. The head
is the farthestmost boundary-line – when
you are farthest from your being, you are in
the head. When you are close to your being,
you are in the heart. When you are at the
very core of being, you are in the hara.

And only through the hara, fear disappears.
Only through the hara do you live for the
first time authentically, sincerely, with no
fear. And that life needs to be lived...
