Crutches.  You lean on
them when you have a need.  They are a
temporary measure until you can stand on your own two feet again.  When trying to attune to Higher Consciousness
there are a variety of devices you can lean upon to aid the process:  pendulums, divination cards, scrying boards,
and the like.  None of these are
bad.  All can be helpful, but like
crutches, all are merely aids until you can stand on your own and hear the
voice, and feel the sensations, and decipher the signals that Higher
Consciousness uses to communicate.  Use
your crutches if they are helpful, but do not become dependent upon them.  It is through the use of your God-given
abilities that they grow stronger.
