Chapter 3: How to Listen to and Explain the Teachings
Page 66 lists individuals to whom one should not give teaching.
However, can someone clarify the prohibition attributed to Gunabhadra against giving a teaching to someone whose head is wrapped in a cloth?
I'm assuming this refers to an individual of another religious group (perhaps Sikh or Muslim) and relates to the proscriptive prohibition in Chapter 12 from the MPN sutra against befriending non-Buddhist philosophers (p 194).
If this is the case I assume it could also relate to the unfavorable rebirths listed in Chapter 7 from Nagarjuna's Friendly Letter, "an uncultured person in a border region" (p118).
