大毘盧遮那成佛經疏 8.40

8.40

"As at the celebration when he eradicated the various
Sufferings of household life,
With a joyous heart in the middle of the night,
He proceeded to the place of austerities;
And just as the heavenly hosts
Paid homage, circumambulating him,
You now obtain a celebration identical to that,
A joyful celebration of making tranquility."
