I am studying the Qabalah and the tree of life with Spirit Science. They have lessons that will walk you through the lessons.
Complaining keeps us locked in negativity, right? I mean, think about it. Who wants to hang out with someone who complains all the time? No one. So why complain even to yourself? This is the source from which self-disgust, self-hatred, and self-sabotage springs—and the ego loves it, this self-imposed separation.
If we are able to maintain this practice [of not complaining] the results are profound. When we complain, what we are doing is telling a story to ourselves in our minds and then verbally telling others about our personal response to what is taking place in our lives. The story centers on how an event affects ‘me.’ In an instant, we are able to see that we have bought into the validity of our thoughts and opinions and we want to broadcast them.
