I see you as part of a greater tapestry of life, a greater tapestry of life in this time, in this world, in this place, in these circumstances, for the tapestry is changing. Let us not confuse, then, your life within the world withyour life beyond, for they are different. If you think they are the same, you will underestimate your life beyond the world, and you will overestimate your life within the world, and you will make some grave misinterpretations of your abilities and your nature while you are here. You are working in a very limited context. You have physical and mental limitations while you are here. You have experienced these limitations, perhaps painfully, but you need to understand them, and you need to recognize them without self-condemnation, for you have limits. You are working through a limited vehicle in your body and a limited vehicle in your mind. The spirit of you, which we call Knowledge, must exercise its Wisdom and its beneficence and its purpose through these limited vehicles and through the circumstances that you face in everyday life.
