The source of all problems

Where do all our sorrows and problems come from? The answer is: your deluded mind. We cannot control the environment and circumstances around us. Partly they appear due to our wrong choices in the past and karma from beginningless lives. Well, what is done is done. We can do confession for unripened karma but this will not help our present situation. But why is it that some people thrive due to adversities and some people wither? The difference is in the way the mind is trained. If you firmly believe that what is happening is real, if you think that it is never your fault, if you choose to wallow in self-pity, then who is to be blamed for your suffering? If you think that what is happening is like a nightmare which will soon pass, if you take this chance to think of all the other people in the same situation and arise compassion for them, if you do not choose to be sad but instead strive to do what is right in each situation, your mind will remain calm and happy. So what is your choice today, to suffer or be happy?
