are two kinds of fear.
There's the kind of
fear caused by something happening outside of you. For
example, you're crossing a street, and suddenly you see an
automobile bearing down on you at high speed.
That's a good kind of
fear. It'll activate your instinct for survival, causing
you to do automatically whatever is necessary to get yourself out of
danger. And its effect on your body is minimal.
And then there's
the kind of fear caused by something happening inside of you. For
example, you become afraid when you hear a rumor that there will be
extensive layoffs in the coming year.
Now that's a bad
kind of fear. It'll paralyze your thinking, rendering you
essentially helpless. Moreover, if sustained over a period of time,
and it usually is, it'll ravage your body.
Now what is the
fundamental difference between the two?
The first kind of
fear is imposed upon you by something over which you have
no control, something that's actually happening, something that
poses an imminent threat of harm. Which means that you don't choose
to be afraid, you instinctively are afraid.
But the second
kind of fear is self-imposed, because it's your response to
what is nothing more than a string of words that you decode and
color according to your habitual state of mind. There's nothing
that's actually happening, nothing that poses an imminent threat of
harm.
Which means that
you don't have to be afraid, you choose to be
afraid.
Are you locked into that
state of mind? No. You're the one who chose to make it
habitual. No one else did. And you're the one who can unchoose to
make it habitual. No one else can.
Think about it.
