He should not be biased by favoritism: How is one biased by favoritism? It may be that someone thinks, “This is my preceptor, teacher, student, pupil, co-student, co-pupil, friend, companion, or relative.” To be compassionate toward and protect this person, he proclaims what is contrary to the Teaching as being in accordance with it and what is in accordance with the Teaching as contrary to it. He proclaims what is contrary to the Monastic Law as being in accordance with it, and what is in accordance with the Monastic Law as contrary to it. He proclaims what hasn’t been spoken by the Buddha as spoken by him, and what has been spoken by the Buddha as not spoken by him. He proclaims what was not practiced by the Buddha as practiced by him, and what was practiced by the Buddha as not practiced by him. He proclaims what was not laid down by the Buddha as laid down by him, and what was laid down by the Buddha as not laid down by him. He proclaims a non-offense as an offense, and an offense as a non-offense. He proclaims a light offense as heavy, and a heavy offense as light. He proclaims a curable offense as incurable, and an incurable offense as curable. He proclaims a grave offense as minor, and a minor offense as grave. If he is biased by favoritism by way of these eighteen grounds, then his behavior is unbeneficial and a cause of unhappiness for humanity; it is harmful, detrimental, and a cause of suffering for gods and humans. If he is biased by favoritism by way of these eighteen grounds, then he is damaged and impaired, blamed and criticized by sensible people, and makes much demerit.
