Consider whether great changes have not happened deep inside your being in times when you were sad. The only sadnesses that are unhealthy and dangerous are those we carry around in public in order to drown them out. Like illnesses that are treated superficially, they only recede for a while and then break out more severely. Untreated they gather strength inside us and become the rejected, lost, and unlived life that we may die of. If only we could see a little farther than our knowledge reaches and a little beyond the borders of our intuition, we might perhaps bear our sorrows more trustingly than we do our joys. For they are the moments when something new enters us, something unknown. Our feelings grow mute in shy embarrassment, they take a step back, a stillness arises, and the new thing, which no one knows, stands in the midst of it all and says nothing.
— Rilke, Borgeby gärd, Sweden, August 12, 1904
