Harmony is a Science

This is the century celebration of the final rendition of the capitalized version and order of The Seven Synonyms of God, revealed to Mrs. Eddy in 1907-2007.

From the big blue book 'The Seven Synonyms for God by Max Kappeler'

We know harmony is an idea character of
principle; Harmony consists in frictionless relationships, governed by a
system; This main tone may be further supported by sub tones, showing for
example; 'harmony is created from the intelligent interrelationship of
ideas" and so rests on law (Mind); In harmony everything unfolds according to a
definite order, which is spiritual, not material (Spirit); Harmony controls
everything through the rule, that the greater controls the lesser (Soul);
Harmony maintains its self by the method of 'perpetual self renewal'
Therefore cannot run down or deteriorate (Life); Harmony redeems, heals, saves,
because it always affirms the facts of being & claims there true ideal form
(Truth); It is holistic integrating everything into one whole, it is
impartial; never exclusive (Love)
