You haven’t forgotten your Presence.
Maybe your mind has. But your mind isn’t supposed to know it anyways. Your mind cannot see what cannot be seen.
You cannot forget. Forgetting your Presence while you are awake, would be like forgetting what a tree looks like as you stand amidst a forest.
You cannot forget your Presence while you are Present. While your mind is worrying about what it has “forgotten,” there You are, Present beneath the worries. Surrounding your mind like a forest, as it searches desperately for a “tree.”
