Buddha Vacana (October 23, 2555)
Possessing five qualities, one who nurses the sick is fit to nurse the sick. What five? He can prepare the medicine; he knows what is good and what is not. What is good he offers, and what is not he does not; he nurses the sick out of love, not out of hope for gain; he is unmoved by excrement, urine, vomit and spittle; and from time to time, he can instruct, inspire, gladden and comfort the sick with talk on Dhamma.
-- A.III,143 (Anguttara book III verse 143; as copied from DPR)
<Note: This description of a nurse in the Buddha time is quite interesting. This verse suggests that nurses (then) were what we 'would die' to have today.>
