‘Just as there is room in the sky for a thunderstorm, so there is room in the vast space of our mind for a few painful feelings; and just as a storm has no power to destroy the sky, so unpleasant feelings have no power to destroy our mind.  When painful feelings arise in our mind, there is no need to panic; we can patiently accept them, experience them, and investigate their nature and where they come from.  When we do this, we shall discover that painful feelings do not come to us from outside but arise from within our own mind.  Circumstances or other people have no power to make us feel bad; the most they can do is trigger the potentials for painful feelings that already exist within our own mind’ ~ Geshe Kelsang Gyatso - How to Solve Our Human Problems.
