19 abhivāyaṇam abbhuṭhāṇaṃ | sāmī kujjā nimantaṇaṃ /
je tāiṃ paḍisevanti | na tesiṃ pīhae muṇī ||38||

It may be that a gentleman salutes a monk, or rises from his seat on his approach, or invites him (to accept alms in his house): a monk should evince no predilection for men of this sort, who show him such marks of respect. (38)
Not resentful, having few wants, begging from strangers, and not being dainty, a wise man should not long for pleasant things, nor be sorry afterwards (for not having got them). (39)
