Time Tunnel

Two boys vacationing in the forests of the Transylvanian alps discover a ruined laboratory, a recently deceased dinosaur, and a mysterious humming tunnel. Donny and Bobby, guided by a grown-up named Hansel, travel back in time to meet sages, villains, and common citizens, then forward to an age of spiritual enlightenment only a sage like Kriyananda could imagine and describe. Whether fact or fiction (the author remains vague on the point), this book contains more truth than many a ponderous volume of philosophy gathering dust on a library shelf
