Buddha's last words

Pastor Rony Tan of Lighthouse Evangelism claimed that the dying Buddha's last words was "I am still searching for the way." Actually I think he was just joking. Anyway, for those who are curious, last words of Buddha can be found in Mahāparinibbāna Sutta (大般涅槃經). "Behold, O monks, this is my last advice to you. All component things in the world are changeable. They are not lasting. Work hard to gain your own salvation."
