One who drinks wine, one who hates others, one who is angry, one who is merciless, one who feels pain on seeing other's happiness, one who injures friends, one who always kills living creatures, one who is ungrateful, one who is vile, should be shunned. Friendship should never be contracted with any of them. Likewise, no friendship should be made with him who is always busy with seeing the faults of others. Listen now to me as I mention the persons, with whom friendship may be contracted.
