With all my wiry power and strength, I am prone at times to bodily sufferings, connected chiefly with the digestive organs, of no common degree or king. I do not regret the sufferings and peculiarities of my physical constitution. They have taught me, and continue to teach me, that which I think nothing else could have developed. It is a force and control put upon me by Providence which I must obey. And the effects of this continual disciple of facts are mighty. They tame the in the best sense of that word, and they fan into existence a pure, bright, holy, unselfish flame within that sheds cheerfulness and light on many.
In a letter to Andrew Crosse, as quoted in Eugen Kölbing's Englische Studien, Volume 19 (1894), Leipzig; O.R. Reisland, "Byron's Daughter", p. 158.
