345. Now, on one occasion, the Lord rose from solitude towards evening and sat warming his back in the westerly sunshine. Then, Venerable Ānanda came to see the Lord and while massaging his limbs with his hands he said: “It is strange, it is wonderful, how the Lord’s skin is no longer clear and radiant, how all his limbs are slack and wrinkled, how his body is stooped, and how his sense faculties have changed.” 
    The Lord replied: “So it is, Ānanda, so it is. Old age is inherent in youth, sickness in health, and death in life.”
