“The destiny of the spiritual World, and, — since this is the substantial World, while the physical remains subordinate to it, or, in the language of speculation, has no truth as against the spiritual, — the final cause of the World at large, we allege to be the consciousness of its own freedom on the part of Spirit, and ipso facto, the reality of that freedom.”

Context: I believe that any "awareness" of life is "spiritual" since awareness can only be a quality of the spirit not of the material world or of matter and machines. Only a spiritual being has awareness. But if you mean "spiritual" in the sense of a kind of "celebration of Life", then yes, I write music to celebrate life. I think most artists do, no matter how they themselves describe it. It's the joy of creating. It's a way of life.

Context: Science is the language of the Temporal world, Love is that of the Spiritual world. Thus man takes note of more than he is able to explain, while the Angelic Spirit sees and comprehends. Science depresses man; Love exalts the Angel. Science is still seeking, Love has found. Man judges Nature according to his own relations to her; the Angelic Spirit judges it in its relation to Heaven. In short, all things have a voice for the Spirit.

Elements of the Philosophy of Right (1820/1821)
Context: The good is the idea, or unity of the conception of the will with the particular will. Abstract right, well-being, the subjectivity of consciousness, and the contingency of external reality, are in their independent and separate existences superseded in this unity, although in their real essence they are contained in it and preserved. This unity is realized freedom, the absolute final cause of the world. Addition.—Every stage is properly the idea, but the earlier steps contain the idea only in more abstract form. The I, as person, is already the idea, although in its most abstract guise. The good is the idea more completely determined; it is the unity of the conception of will with the particular will. It is not something abstractly right, but has a real content, whose substance constitutes both right and well-being.
