You will fall sick, experience pain, and encounter many adverse circumstances. At such times do not think : ‘Although I am practicing the Dharma, I have nothing but trouble. The Dharma cannot be so great. I have followed a teacher and done so much practice, and yet hard times still befall me.’ Such thoughts are wrong views. You should realize that through the blessing and power of the practice, by experiencing sickness and other difficulties now, you are purifying and ridding yourself of negative actions…. By purifying them while you have the chance, you will later go from bliss to bliss. So do not think, ‘I don’t deserve this illness, these obstacles, these negative influences.’
Experience your difficulties as blessings…when you do experience such difficulties, you should be very happy and avoid having adverse thoughts like, ‘Why are such terrible things happening to me?’
