妙法蓮華經玄贊 5.192

5.192

The subsequent text itself says: 'The elder, having heard this, entered the burning house in alarm,' and in the application of the metaphor, it says itself: 'For the benefit of sentient beings, he was born into the dilapidated burning house of the three realms.' / The Nirvāṇa Sūtra says: 'For example, if a fire breaks out in an elder's house, the elder, seeing this, escapes from the house. His sons are behind, not yet free from the disaster of the fire. The elder at that time certainly knows the harm of the fire, but for the sake of his sons, he turns back to rescue them without regard for the danger. The buddhas and bodhisattvas are also like this: although they know that saṃsāra has many faults and perils, for the sake of sentient beings they dwell in it without revulsion; therefore it is called inconceivable.' / Hence, it is again manifested that he escapes together with the sons, but in reality the Buddha escaped before.
