The words that you refer to are the coda at the end of a long (12 minutes+)song called "A very cellular song". This may be found on the 1968 album The Hangman's Beautiful Daughter and was the last track on side one of the original vinyl disc - now it is track 4 on the CD.

Essentially it is a three chord trick that would be, say, D,G,A,D,G,A or whatever for the key you are in. The words are:

"(D)May the long time (G)sun shine on (A)you, all love (D)surround you, and the clear light (G)within you (A)guide you all the way (D)on" repeated endlessly to the fade.

Hope this helps
