I inherited spirituality from my parents but I only became clear on the concept when Oprah's fave book came out.  Dr. Melvin Morse, Seattle Children's Hospital, 1994.  His concepts have recently been proven by two PEER REVIEWED 
papers from U. of Washington:  "Recycled souls" (the Jews are right!) and "Wi-Fi without hardware" (the Hopi are right!).  All that is needed to be spiritual is an open mind and an open heart.  Rare?  E-zay!  "Google it".  Computer wonks can access the "partition" of the human brain, "administrator permission required" for hard-drives of past lives.  "Inherited knowledge" went viral, 2015, when us math boneheads passed the Math part of the Mensa test.  Whodathunkit!
