152. A man who has learnt little, grows old like an ox; his flesh grows, but his knowledge does not grow.
153., 154. Looking for the maker of this tabernacle, I shall have to run through a course of many births, so long as I do not find (him); and painful is birth again and again. But now, maker of the tabernacle, thou hast been seen; thou shalt not make up this tabernacle again. All thy rafters are broken, thy ridge-pole is sundered; the mind, approaching the Eternal (visankhâra, nirvâna), has attained to the extinction of all desires.
DHAMMAPADA, Chapter 11. Old Age
