The quality of being directed toward heaven; the state or characteristic of moving upward or toward the divine.
From 'heavenward' + '-ness' (suffix creating abstract nouns). This creates a noun expressing the abstract quality of having a heavenward direction or inclination. The triple suffix formation (heaven-ward-ness) shows English's ability to layer meaning.
Triple-suffixed words like 'heavenwardness' are rare and show English's incredible flexibility—we can stack suffixes indefinitely to create new meanings, though such words are usually only used when writers want to emphasize something very specifically!
