derivation of symbols on the 10 bodies

Guru Dharam Khalsa or Darryl O'Keeffe Could you please tell me the derivation of the symbols for the 10 bodies in your book The Kundalini Yoga Experience? I can't find these anywhere else in my KY references. Did it come from YB or conscious communication or your creative mind? Many thanks, Mantra Simran Singh ((( Darryl writes: Credit here is due to Creative Mind )))
