Among the Japanese lives a certain sect, who keep an interesting custom, viz two people loving each other very much don't go together to worship their God, which they call a jealous God, as they believe this God will spoil their love. The idea underlying this belief is that a love which is not allowed to spread, but which is kept in narrow bounds, as the water in the little tank, is spoiled by the same spirit that spoils the water. By this man learns the lesson that progress of love is life and its stillness death.
