Some Cayce quotes to get you started:
Music should be a part of each soul's development. (2780-3)
(Q) How much attention may I justifiably give to music, which I love so much?
(A) This should be ever rather as the hobby, fulfilling. For, oft ye will find the music alone may span the distance between the sublime and the ridiculous. So it is in the search for God, that haply ye may find Him, for He is within thine own self. (3188-1)
For Life is in all phases the manifestation of that which is called Divine, Creative, or God in the experience of man. (1568-3)
But stay close to music, close to those things of the art and artist temperament. For these bespeak of those things of the spirit. For, as music is of those activities that span the differences, so is art an expression that reminds one of those things that may attune the mind oft to the realms easily forgotten... Who may tell the rose how to be beautiful? Who may tell the snow how to be white? These come from the experience of the entities that attune themselves to God. These ye will find, then, in thy music, in thy home, in thy love for art. In these ye may find the outlet. Teach others - by precept, yes, but most of all by pattern. (3253-2)
(Q) What would God have me do with the rest of my life?
(A) As has been indicated, directing the life of the early teen-age girls. Do use music in same. (5112-1)
So may the entity in the present in the ministering as in music. For the entity may attain or attune self to the infinite more in music than in any other form or manner of activity. (3272-1)
From the aspects in Venus we find the home loving individual, the home making; the enjoyment of beauty and of every form of art - as music, which is at times that alone which may bridge the distance from the material to the spiritual. (2280-1)
In music the entity finds MUCH solace, MUCH that bridges those distances - whether of the mental or of the spiritual forces. In same the attunement of self may be brought the nearest to the applications of the innate FORCES of self, and to the ENTITY the strains of same - whether in that of the deep vibrations, of those that raise up and up – or those of the higher chords that bind - carry for the entity the ATTUNEMENT of self in the sphere or element, or PHASE of experience the entity seeks apace. Well were THIS developed to a more acuteness IN this PRESENT experience, for the acumen of experience to the entity is gained MUCH more in a manner that may become concrete ensamples of the attunement of a soul with the heavenly, or the happy, choir. (115-1)
In music, and especially the piano, lies the direction of activity. Do not let material things hinder. Ye must know pain, ye must know sorrow, if ye would depict same in thy music. CREATE those forces within thyself; then as to what and influence means that brings peace on earth, good will to men. (1815-1)
Thus we find the entity building into the experience of self, as well as into the hearts and minds and experiences of others, the appreciations of all those things of a material nature, as well as mental and spiritual, that bring the proper evaluation of the experiences of those who know art, music, song, the earth and nature and its expressions of GOD! (2117-1)
As has been indicated, music becomes to the entity a means of expression that bridges much of that which may bring beauty and harmony into the experience of the entity; and it is then one of the channels in which and through which the entity may bring to self much of the beauty and harmony that has been lost by the turmoils of the minds of men about the entity. (412-9)
(Q) Would you advise that I continue my work relative to music?
(A) As an example of the unison and rhythm of life, yes. As that which may supply oft that which bridges space or time, well.
(Q) What do you advise regarding my work in writing fiction?
(A) If this is based upon the FINDINGS in the mental and spiritual, well - for THESE would make for an awakening to the many. (1135-1)
Do give the opportunity for music. Let the entity listen to and be guided by, not that character of music that is of the passing fancy but that which builds harmony, that which builds the bridge between the sublime and the finite – or from the infinite to the finite mind. Cultivate these more often in the body-mind as it unfolds. Thus we will find less and less of this tendency for headstrongness. (4098-1)
Though there have been foes and enemies made, then, these should not be held as that which produces fear or doubt in the experience of the entity. For, learn – in music, in art, as well as in all phases of human experience - "KNOW, O MAN, THE LORD THY GOD IS ONE!" (2132-1)
Each appearance of the entity in the earth needs its individual analysis, that the temperaments, the latent urges, the influences wrought by the vibrations, by the color, by the harmony, yea by the very INHARMONY among associates, may be understood as to the effect had upon the feelings of the entity. For the experience becomes rather as a very delicate instrument of music upon which the chords of life (which is God) are played. (2117-1)
Who may tell a poem to give censure or praise? Who may tell a rose to be sweet, or the music of the spheres to harmonize with God? (2408-1)
The music of the reed and stringed instruments were a part of the entity's activity in that experience. Thus, as indicated, it may oft span distances for the entity, bring up memories, put away fears, bring close the spiritual import, remind the entity of an embrace, a moonlight walk or a drifting along life's tide - with certain ideas (don't call them, too oft, ideals; their associations, yes), but make them realities in the experience of someone, and they become real to thee. (2936-2)
Let me, O God, in my music, in my heart, give that which is as helpfulness to that in the lives of others." (5265-1)
(Q) Shall she make a success of writing? What is the best way to go about it?
(A) Write, first, alone. Write in that manner as of REARING the children of the mental being. Be not afraid of these, for these will NOT destroy the personality - but will CERTAINLY enlarge the INDIVIDUALITY and soul of the body. (5439-1)
(Q) Should I attempt to foster my apparent latent ability for inspirational writing?
(A) This should come rather a little later, as there is builded in the inner experience the beauty and hope of such as thy work brings into the minds and hearts of others. Let's for the moment illustrate these; that the entity may gather as to what inspiration really means. It is not of influences without, but the ANSWER to something WITHIN. The real inspiration is the arousing of a consciousness of that WITHIN! As one beholds the paintings (we would say) of the Last Supper, or the Virgin, or the Flight into Egypt - and these are new, or these have not been beheld by the individuals before - there is seen the awe, the love that flows into the heart and soul of the beholder. Then such an one (gifted as thyself) may, beholding same, become inspired as were those who depicted these. Not for the preservation of same as history, nor as even a place, but - as has been indicated - the day is arriving - the day is at hand - when it is neither in the temple nor in the mountain but in the HEARTS of men that the worship and the glory of God is beheld! (1597-1)
Each appearance of the entity in the earth needs its individual analysis, that the temperaments, the latent urges, the influences wrought by the vibrations, by the color, by the harmony, yea by the very INHARMONY among associates, may be understood as to the effect had upon the feelings of the entity. For the experience becomes rather as a very delicate instrument of music upon which the chords of life (which is God) are played. (1436-2)
