"The men of mighty will the world has produced have all been tremendous workers - gigantic souls, with wills powerful enough to overturn worlds, wills they got by persistent work, through ages, and ages. Such a gigantic will as that of a Buddha or a Jesus could not be obtained in one life, for we know who their fathers were... Millions and millions of carpenters like Joseph had gone; millions are still living. Millions and millions of petty kings like Buddha's father had been in the world. If it was only a case of hereditary transmission, how do you account for this petty prince, who was not, perhaps, obeyed by his own servants, producing this son, whom half a world worships? How do you explain the gulf between the carpenter and his son, whom millions of human beings worship as God? It cannot be solved by the theory of heredity. The gigantic will which Buddha and Jesus threw over the world, whence did it come? Whence came this accumulation of power? It must have been there through ages and ages, continually growing bigger and bigger, until it burst on society in a Buddha or a Jesus, even rolling down to the present day."
