Some Cayce quotes to get you started:
DO NOT hold the idea, "Well, I know what they are going to say or do, but I'll do as best I can." Disregard that! KNOW the spirit with which YE do a thing is the spirit that will respond to thee! (1688-9)
The Spirit is the movement; as when God the First Cause - called into being LIGHT as a manifestation of the influences that would, through their movement (light movement) upon forces yet unseen, bring into being what we know as the universe – or matter; in all its forms, phases, manifestations. (262-119)
For movement is the effect of spirit. Spirit is life. (705-2)
For as there is indicated, it is the MOVEMENT of spirit upon things that do not appear that has brought into being the things that DO appear … (1486-1)
For, thou art in thyself divine! The mere fact or knowledge of thy existence in a material world, prompted by the activities or the movement of the Spirit itself, indicates thy own divinity; but to be attained! (1709-3)
There is progress whether ye are going forward or backward! The thing is to move! (3027-2)
Thus as has been indicated, the Spirit pushed into matter - and became what we see in our three-dimensional world as the kingdoms of the earth; the mineral, the vegetable, the animal - a three-dimensional world. And that which beareth witness is the Spirit of Truth, the Spirit of Light. For He said, "Let there be light; and there was light." Then indeed there is no power that emanates that is not from God. Then what is this Spirit of Rebellion, what is this Spirit of Hate? What is this Spirit of Self-Indulgence? What is this Spirit that makes men afraid? SELFISHNESS! Allowed, yes, of the Father. For, as given, He has not willed that the souls should perish but that we each should know the truth - and the truth would make us free. Of what? Selfishness! (262-114)
All SPIRIT is ONE. How? Just as all force, all power emanates from that influence, that essence, that consciousness, that awareness which the consciousness of man - or man as the image of the Creator - worships. (262-115)
Keep the attunement to the spiritual forces, for it is the SPIRIT that gives life - but life in a physical functioning is of physical reaction. (2095-1)
(Q) Is there any advice I can now have to live better in the eyes of God and man?
(A) As we have indicated again and again - thou knowest the faith - thou understandest. Live not only by the letter of the law but the spirit of same. For, the letter maketh afraid - the spirit giveth life. (257-229)
For the spirit is life; the mind is the builder; the physical is the result. (349-4)
