Part of the greatness of Amichai is that people write brilliantly about him. I meant to distill this essay by Adam Kirsch but there's too much of it. Like a poem, you can't condense or summarize & keep any of the flavor.
Here's a line I liked:
The Jewish vocabulary of Amichai's poetry doesn't mean that he is a believer. On the contrary, the deep pathos of his religious verse is that he has achieved a kind of sublime intimacy with a God who does not exist, at least not as the tradition conceives Him.
I always return to Amichai.
