阿彌陀經通贊疏 3.109

3.109

作禮而去者，是第四退辭佛去。五輪俱屈，三業歸誠，咸別世尊，各還本土，故云作禮而去。

As for 'paid homage and departed', this is the fourth, taking leave of the Buddha and departing. With the five limbs prostrated and the three karmas offering sincerity, all took leave of the World-Honoured One and returned each to their own land; therefore it says 'paid homage and departed.'
