Some Cayce quotes to get you started:
For all prayer is answered. Don't tell God how to answer it. (4028-1)
For prayer is supplication for direction, for understanding. Meditation is listening to the Divine within. (1861-19)
Then set definite periods for prayer; set definite periods for meditation. Know the difference between each. Prayer, in short, is appealing to the divine within self, the divine from without self, and meditation is keeping still in body, in mind, in heart, listening, listening to the voice of thy Maker. (5368-1)
What IS Meditation? It is not musing, not daydreaming; but as ye find your bodies made up of the physical, mental and spiritual, it is the attuning of the mental body and the physical body to its spiritual source. Many say that ye have no consciousness of having a soul, – yet the very fact that ye hope, that ye have a desire for better things, the very fact that ye are able to be sorry or glad, indicates an activity of the mind that takes hold upon something that is not temporal in its nature, – something that passeth not away with the last breath that is drawn but that takes hold upon the very sources of its beginning – the SOUL, – that which was made in the image of thy Maker – not thy body, no, – not thy mind, but thy SOUL was in the image of thy Creator. Then, it is the attuning of thy physical and mental attributes seeking to know the relationships to the Maker. THAT is true meditation. (281-41)
MEDITATION is EMPTYING self of all that hinders the creative forces from rising along the natural channels of the physical man to be disseminated through those centers and sources that create the activities of the physical, the mental, the spiritual man; properly done must make one STRONGER mentally, physically, for has it not been given? He went in the strength of that meat received for many days? Was it not given by Him who has shown us the Way, "I have had meat that ye know not of"? As we give out, so does the WHOLE of man – physically and mentally become depleted, yet in entering into the silence, entering into the silence in meditation, with a clean hand, a clean body, a clean mind, we may receive that strength and power that fits each individual, each soul, for a greater activity in this material world. (281-13)
Depend more upon the intuitive forces from within and not harken so much to that of outside influences – but learn to listen to that still small voice from within, remembering as the lesson as was given, not in the storm, the lightning, nor in any of the loud noises as are made to attract man, but rather in the still small voice from within does the impelling influence come to life in an individual that gives for that which must be the basis of human endeavor … (239-1)
(Q) How can I overcome the nerve strain I'm under at times?
(A) By closing the eyes and meditating from within, so that there arises – through that of the nerve system – that necessary elements that makes along the PINEAL (Don't forget that this runs from the toes to the crown of the head!), that will quiet the whole nerve forces, making for that – as has been given – as the TRUE bread, the true strength of life itself. Quiet, meditation, for a half to a minute, will bring strength – will the body [if the body will] see PHYSICALLY this flowing out to quiet self, whether walking, standing still, or resting. Well, too, that OFT when alone MEDITATE in the silence – as the body HAS done. (311-4)
(Q) Why don't I have more success with meditation?
(A) Oft we find individual activity becomes so personal in even the meditations that there is sought that this or that, which may have been reported to have happened to another, MUST be the manner of happening to self. And in this manner there is cut away, there is built the barrier which prevents the real inner self from EXPERIENCING. Let self LOOSE, as it were; for thy prayer ascends to the throne of grace, ever; only as self, though, metes out to thy fellow man. Do not TRY, or crave, or desire a sign; for THOU art in THYSELF a sign of that thou dost worship within thine inner self! For thou, as every soul, dost stand before the door of the temple where thy God hath promised to meet thee. Then, do not be impatient. For what thou asketh in secret shall be proclaimed from the housetop. (705-2)
(Q) Has nervous intensity devitalized the thinking brain cells?
(A) Rather as indicated. Then, to overcome, as has been indicated, MEDITATE! Meditation means entering into the SPIRITUAL vitalization of the energies of the system, by RAISING those forces through the very activities of procreative actions. Read MEDITATION [A.R.E. paper which later became 1st chapter in A SEARCH FOR GOD, Book I.], and apply it – PRACTICALLY – the experience of self! (270-33)
(Q) Is there a meditation that can be used for building the body and keeping it in good condition? Please explain how this might be accomplished?
(A) Just as the suggestions may be used that have been made to the body through some of the treatments outlined, – the MIND acts upon the resuscitating forces of the physical being, by and through suggestion. Just so there may be the realization that spiritual forces are a part of the whole physical being. For, the REAL being is the spiritual import, intent and purpose, see? Thus a meditation, a centralizing, a localizing of the mind upon those portions of the system affected, or upon the activities needed for the physical being, INFLUENCES, directs the principal forces of the system. And it does resuscitate, if kept in sincerity; not merely said as rote, but that said being put into practical application through the experiences and associations with others, – and especially this entity as it works with the developing minds, may see such reactions.
In the meditations, then, OPEN the mind, the being, to the influences about same; surrounding self with the consciousness of the healing that is in the Christ-Consciousness, the Christ-awareness.
LORD, USE THOU ME – MY BODY, MY MIND – IN SUCH A WAY AND MANNER THAT I, AS THY SERVANT, MAY FILL THOSE LIVES AND HEARTS AND MINDS I MEET – DAY BY DAY – WITH SUCH HOPE AND FAITH AND POWER IN THY MIGHT, THAT IT MAY BRING THE AWARENESS OF THY PRESENCE INTO THE EXPERIENCE OF OTHERS AS WELL AS MYSELF.
Such as these will bring those forces and influences for helpful experiences for the body. (1992-3)
