Letter to Thomas Walpole (19 February 1785)

Reverence for Life (1969)
Context: I do not want to frighten you by telling you about the temptations life will bring. Anyone who is healthy in spirit will overcome them. But there is something I want you to realize. It does not matter so much what you do. What matters is whether your soul is harmed by what you do. If your soul is harmed, something irreparable happens, the extent of which you won't realize until it will be too late.
