[...] Last autumn Wesendonck informed me of his Guido's death in a very moving letter. I answered him in the same tone, and since then we have been in friendly correspondence from time to time. However, it was not this which decided me to settle in Lucerne; for though I had proposed to the Heims that I should visit them this summer I did not propose to go near Zurich. But then a few days ago I got an invitation from Wesendonck; I was to put up at his house, he would send a carriage to the station to meet me, and he gave me to understand that he intended to put an end to exaggerated and mistaken rumours by this open act of friendly intercourse. So I accepted, travelled to Zurich last Saturday, got into Wesendonck's carriage, slept the night at his house and returned on Sunday afternoon, having gone in W.'s carriage again in the morning to the Zeltweg, and visited the Heims by myself. This was, as we both hope, a very salutary demonstration, and everyone will naturally infer from it how I stand with the family; of course, it has already made a great impression on the servants. He was very cheerful and happy and I, no less, am relieved of a great source of worry. You too, I hope, will draw from this the same conclusions which reassured Wesendonck. Before I leave Switzerland altogether, I am thinking of accepting his further invitation, when a larger party is to be invited.—
I need hardly tell you that this will not make the least difference in my, and our, mutual arrangements for the future. Everything remains as we settled it. Only now everything in the past is clear and bright to me—and to you too, I hope—so that no clouds nor mists remain to be dispelled. [...]
