Peace like a river … a very apt phrase for describing the way the vibration of love does flow through you.  Why do you say that you feel warm in your heart when love is present?  Understand that love is always present, but when allowed to flow freely, the higher energy of this highest of vibrations produces an actual heat.  A healer’s hands become hot from this healing energy of love, do they not?  And always it does flow—yes—like a river, stopped only by the thoughts which dam it.
Staunch not this vital flow, but seek out the blockages so that the warmth fills not only the heart, but all of your being.  There you will find true peace, in the depths of the river of love.
