3.111

Third, difficult forbearance (duṣkarakṣānti), has three kinds: enduring harm done by inferior sentient beings is called the first difficulty. Residing in an exalted position, being able to endure harm done by one's own servants and subordinates is called the second difficulty. Being able to endure intense harm done by sentient beings of low caste and slavelike status is called the third difficulty.
