Mistakes happen because of ignorance, lack of knowledge, lack of awareness; some craving or aversion due to which you committed a mistake. That is done, finished. The moment you realize a mistake, you are out of it at that moment. So, don’t be too hard on yourself. And never ever think of ending your life. Got it?
And if you find someone else also doing that, just bring them to the Part 1 course. Let them do breathing, let them meditate and you’ll see they will also get out of this tendency.
