This book is a narrative of lessons told in a 60+-year Tutelary Exemplar, or Guardian Teacher relationship between a Sáami ancestral spirit and the author. Here we find a medicine man Spirit dispensing guidance not just to his apprentice, but, to all people of all races. Sáami/American Author H.D. Rennerfeldt has embarked the reader on an autobiographical voyage into his intellectually enlightened inspirations. Many of the life tutoring is wonderfully intriguing especially the didactic passages on the Jimmy Hoffa disappearance. This is a far cry from the failed attempts by the F.B.I. and the gangsters looking to cash in on a mystery. “The most incomprehensible thing about the world is that it is at all comprehensible.” -Albert Einstein
