When something happens generally in life, the first action should be to reflect on the thought or lack thereof behind the action. If I did something in a different way then the result would have been different. Our problem lies in the fact that we feel frustrated by what could have been. This bogs us down in the past which affects us in our everyday lives.
In this week's parsha, we continue the story of yosef and his brothers. If you remember, he wasn't treated very well by his brothers. Yet, here he is, viceroy of Egypt, chosen to lead Egypt through what amounts to the Great Depression and now in a position to get revenge on the very brothers that sold him. It's very difficult to say that the brothers were happy with their choice in that moment. The point is that the past can't be changed by the present except through teshuva which was the challenge that the brothers had to traverse.
At times, we get upset and hung up on the after-effects of some previous situation. However, we must keep in mind that we can't change our actions in the past and must break out of the hypothetical thought process that helps depression to seep into our thoughts. Do what your mind/heart desires (Torah and mitzvos) and believe in it! Don't have regret over some past mistake but, instead, move forward with a strong drive to do positive acts to shine a light in the darkness. Let's do something productive! Let's transform the world and bring Moshiach! Good shabbos!
All the best!
