Joy or happiness is what the whole space and being is saturated with. That's why we say that joy is a special wisdom, not from the Earth, but from the Eternal Breath of Life. The whole space sings and sounds on the key of happiness.
The man lives for happiness. All the way of his hard earth is only a preve to the happiness of the Far Worlds, not the earthly, but the Far Ones. Disharmony and destruction are the main note of the Earth. Harmony, joy and happiness are a form of identifying life on the Far Stars, in the Higher Worlds.
We are preparing for them by the whole course of earthly evolution, in them the purpose of man.
