Whatever happens.
Whatever what is is is what I want.
Only that.
But that.
Whatever "what is" is, is what I want.
(Second cup of coffee to the rescue.)
Although is appears three times in a row, it is copular only once, in is what I want.
In "What is", is means exists .
And the second is (Whatever what is is ) means happens to be .
Whatever that which exists happens to be is what I want.

Grammatically, this can be summed up neatly by some ungrammatical use of parentheses: (Whatever (what is) is)
is what I want.
Each phrase in parentheses is a noun phrase and can be substituted by any other noun, e.g., (Whatever (infinity) is)
is what I want.
Another way to disambiguate is to rephrase with a demonstrative: (Whatever (what is) is), that is what I want.
The author of the poem italicizes what is in the original to indicate that it should be regarded as a noun phrase.
It could just as well have been quoted: Whatever "what is" is is what I want.
Or to rephrase with the subject of the main clause in parentheses: (Whatever "what is" is) is what I want.
Hope this helps.

Whatever what is is is what I want.
Let's replace some parts of the sentence with equivalent parts of speech Chicken is what I want.
This is a rather unusual sentence structure, but it is grammatical.
But say I didn't know what "Chicken" is.
"Whatever 'chicken' is" then becomes the noun describing the item you want.
Whatever 'chicken' is, is what I want.
But in this case, the mystery item is not identified as 'chicken', but instead it is called 'what is' Whatever 'what is' is, is what I want.
Put altogether
it makes a lovely garden path sentence .

Whatever what is, is is what I want.
That sentence is not in the poem.
The actual sentence, which the question quoted correctly in context, was Whatever
what is is is what I want.
Without the division into lines of poetry, but retaining the italics:"Whatever what is is is what I want."
I believe the intended effect of putting words what is in italics in this poem is similar to the effect that could have been achieved by putting quotes around the words
"what is": it allows this two-word phrase to be treated as a noun.
Unlike the effect of italics or quotes in this paragraph, however,the noun in question is not the phrase itself, but rather is the thing described by those words.
I might unpack the elements of that sentence in the poem as follows: That which exists and occurs in this universe is what is.
Whatever that is, that is what I want.
I hope you agree that the two words what is were a much more fitting way to express the same thing I tried to express in the first eleven words in the previous paragraph.

I believe this can be understood by adding some missing punctuation.
what is, is This is roughly expressing the idea that things are what they are.
In other words, que sera, sera or whatever will be, will be .
What is is may also be a restatement of happens from the first line.
So: Whatever happens.
Whatever (what is, is) is what I want.
Only that.
But that.
If this interpretation is correct, then I believe the author is trying to express that they want to have the ability to accept things as they happen.
This is somewhat reminiscent of the Serenity Prayer (Wikipedia), which starts as follows: God, grant me the serenity to accept the things I cannot change, Courage to change the things I can, And wisdom to know the difference.

Here is the poem:   Prayer, by Galway Kinnell  Whatever happens. Whatever  what is  is is what   I want. Only that. But that.   I came across this poem as an interesting example of English grammar and how it is actually possible to have three "is" in a row. Can anyone explain the poem's  syntax , especially the sentence:   Whatever  what is  is is what I want.

It could just as well have been quoted:   Whatever "what is" is is what I want. Although  "is"  appears three times in a row, it is copular only once, in  "is  what I want".  The author of the poem italicizes  what is  in the original to indicate that it should be regarded as a noun phrase. This is known as a garden path sentence, which is difficult to  understand without conscious parsing. 'What is' can be understood as  an unknown reality, and the poet is saying that they accept this reality whatever it may be.
