The key to success is learning to just observe whatever comes up during meditation. Be grateful for seeing the truth, even if it is unpleasant. You do not have to react in any way. Definitely do not judge yourself or others. If you wallow in your thoughts or insights, it will keep them around. It is best to view all thoughts, emotions and insights as you would view clouds in the sky. Let them come and let them go."Be grateful for seeing the truth, even it it is unpleasant." Yes, that's it. It's hard, I know. Nevertheless, this particular form of gratitude will revolutionize our lives.
I found the above quotation right here.
