Self-nature is always pure, just as the sun and moon are always shining. It is only when they are obscured by clouds that there is brightness above but darkness below and the sun, the moon, and the stars cannot be seen. But when suddenly a gentle mind blows and scatters all clouds and fog, all phenomena are abundantly spread out before us, all appearing together. The purity of people’s nature is comparable to the clear sky, their wisdom comparable to the sun, and sagacity comparable to the moon. Their sagacity and wisdom are always shining. It is only because externally people are attached to spheres of objects (1) that erroneous thoughts, like floating clouds, cover the self-nature so that it is not clear. […] By taking refuge ourselves is meant to remove evil deeds. This is called taking refuge.
