Thiis was published without credit in The Best Loved Poems of the American People (1936) with the title "Friendship", and since that time has sometimes been misattributed http://www.geonius.com/eliot/quotes.html to Eliot; it is actually an adaptation of lines by Dinah Craik, in A Life for a Life (1859):
Misattributed
Context: Oh, the comfort —
the inexpressible comfort of feeling safe with a person —
having neither to weigh thoughts nor measure words,
but pouring them all right out,
just as they are,
chaff and grain together;
certain that a faithful hand will take and sift them,
keep what is worth keeping,
and then with the breath of kindness blow the rest away.
