The ultimate illusion is to feel that the body is eternal and that all the things you have worked for you can keep. If you have not invested in your soul and glimpsed the inner eternalness of spirit you will be in the hardship of loneliness and disappointment in the attachment.
Dance to the music of your season and rest in the review of your years but remain of the same presence that is not the body but only the viewer and the witness. In doing so the taker of the body will never have captured you, for the soul is eternal and so is the connection to the universe and the knowing.
The earth mind is a great computer that keeps you stuck in the illusion that you think you are a body. When you reach cosmic consciousness you can be of the body and be of the light spirit super consciousness, with one foot dancing in each realm.
