When a word or person or random thought comes to mind, pay
attention.  Your thoughts do not
originate in your head.  They are vibrations
of the One Mind of which you are a part. 
Yes, of course, many times they are “your” thoughts recirculating again
and again in habitual patterns, but far more often than you are aware the
thoughts you think are your own are put there for a reason by your loved ones
on the other side, by your unseen helpers, or by even higher consciousness.  When you become aware of thinking, “Now where
did that thought, memory, image come from?” ask, “Where indeed and why indeed?”  This may very well lead to gifts unimagined,
to wondrous synchronicities, and most especially to the awareness that you are
never alone.
