Interference
If you try to do anything other than understand the situation,
your effort will be a blockage, a resistance, an interference.
You cannot make yourself grow; you can only cease to interfere.
You cannot make yourself happy; you can only stop your judgments.
Growth and expansion are natural; they are the life force itself.
And you cannot predict its direction. If you recall the times
when you have experienced a release, when there was an opening,
you will see that it was always by your understanding something,
by your somehow getting out of the way, by your letting go of
some belief, some resistance, some idea. (Diamond Heart Book 2,
pg 109)

Interference issue
You see, when you have an issue in your life, the
point is not to get rid of it; the point is to grow with it. The
point is not just to resolve the issue; the point is to grow through
resolving it. So, in many ways you can see that maturity has to
do with this growth, this broadening, this depth. (Diamond Heart
Book 1, pg 137)
