Kelsang Gyatso

Our mind is like a cloudy sky: in essence clear and pure, but overcast by clouds of delusions. Just as the thickest clouds can disperse, so, too, even the heaviest delusions can be removed from our mind.

The purpose of meditation is to make our mind calm and peaceful. If our mind is peaceful, we will be free from worries and mental discomfort, and so we will experience true happiness. But if our mind is not peaceful, we will find it very difficult to be happy, even if we are living in the very best conditions.
