singing of angels

[patriarch tychon] was seized with a kind of ecstacy
and overheard the singing of angels,
the beauty of which he was unable to describe;
neither could he at the moment, grasp the words of that song,
but was aware of it only - as the harmony of many voices.
- "a treasury of russian spirituality"
