Intuition

Assuming we can quiet ourselves to the point of hearing that small, quiet voice within, Cayce says we should depend on our intuition more than outside influences. Doing so will make for more constructive results. We should hold an ideal before ourselves, and let any pleasure, fame, or fortune be a result of our living to an ideal rather than having those be the ideal.

From Reading 239-1:

26. (Q) Please advise the body as to how he may best gain control of himself and utilize his abilities to best advantage.
(A) 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; for without the ability to constantly hold before self the ideal as is attempted to be accomplished, man becomes one as adrift, pulled hither and yon by the various calls and cries of those who would give of this world's pleasure in fame, fortune, or what not. Let these be the outcome of a life spent in listening to the divine from within, and not the purpose of the life. We are through.

From Reading 792-2:

The more and more each is impelled by that which is intuitive, or the relying upon the soul force within, the greater, the farther, the deeper, the broader, the more constructive may be the result.
