Clarity, Awareness and Emptiness

"Milarepa had a prophesy that he will have two great disciples: one who would be like the sun and the other who would be like a moon. The disciple who was like the sun was Gampopa and the disciple who was like the moon was Rechungpa."

Here is a doha (spiritual song) that Rechungpa sang about the essential meaning of the view and meditation:

If one doesn't understand the actual nature of appearances, then one is going to continue in samsara.
If one realizes the nature of appearances, then one knows them to be the dharmakaya and there isn't any need to look for any other view.
If one doesn't know how to rest the mind in meditation, then one has to meditate on the mind.

The mind has three characteristics which are clarity, awareness, and emptiness.

Clarity means that there is an unbroken continuum of the mind.
Awareness means one knows exactly what it is that one is doing.
Emptiness means the mind has no true, solid reality.

If one doesn't understand these three characteristics, then many different thoughts will arise.
However, if one is able to rest in a natural uncontrived state then this is the sambhogakaya.

As for conduct, one should just deal with whatever occurs and be totally natural without any fixed plan or system. This is called naturally appearing and naturally liberated conduct.
