寶網經偈云。普遍諸佛土。法王之境界。釋師子人尊。一毛光所照。釋曰。如無量無邊諸佛土。不出一毛頭心地。以智了達者。故云光所照。

A verse in the Ratnajāla Sūtra states:
“Pervading all Buddha-lands,
The realm of the Dharma King,
The Lion of the Śākyas, the Honoured One among humans,
Is illuminated by the light of a single hair.”
Exposition: For instance, immeasurable and boundless Buddha-lands do not go beyond the mind-ground of the tip of a single hair. Because one penetrates this with wisdom, it says: “illuminated by the light.”
