When you have those times, even moments, when your mind is blank, rejoice and welcome them. This is an opening for Him to enter. Our society, believes that a strong mind is an advantage, but this is false if the mind leads instead of follows. Your mind should be like a hammer that is picked up when needed. The hammer does not build the house. You build the house and use the hammer only as a tool.
The stronger you hold opinions, thoughts, and judgments, the less room there is for Him to enter. If this statement angers you, it is your ego which is taking offense, because it wants to lead. It doesn't want to be in the background, and it will come up with any number of devious ways, justifications, or excuses to keep itself in the lead and keep you in bondage. A blank mind, just like an empty blackboard, provides the space on which His thoughts and His Love can come into you and be imprinted. And this is what gives you His peace.
