You aren’t a simple body. You are a body of light and your fluid is your essence. So you deserve to know the deep truth. As a soul you are alive for your contribution. That’s why you will always have next to you the Master to help you in any of your decisions, to show you the path and to advice you for each of your needs. This is his duty because he is the savior of the souls. You don’t need to thank him. But you have to know that when you are sad, you insult him because this means that you don’t want to use him and to valorize his gifts. As a soul you have to make your choice to see or not the harmony.
