I think the tapestry analogy points out a difference between some ways of experiencing spirituality and others. Some people believe that the tapestry won't be revealed until the individual is separated from physical existance, while others are saying that they already experience the oneness of things, and can thus perceive all aspects of the tapestry even while residing in a physical body. For the people who experience oneness, the idea of separateness is an illusion, and has no substance. But for those who experience the perception of separateness, the separateness has purpose, and so is valid in its own way.
