"Now, you all [meaning the students] should look without artifice at [your] vidyā in the sky in front [of you]; vividly without distraction; clearly without support; resting in the state of radiance.
Unless it is a figure of speech, it implies that rigpa (at least in the case of someone who is still a beginner) may be found specifically where one applies mindfulness at a given moment. If you are focusing on the eye consciousness for example, you may be able to integrate that and be in rigpa in your eye consciousness. With this idea in mind, one may consider the various methods for recognizing rigpa to work on the same assumption. Then again, the above quote perhaps would be more correctly read as an instruction not to focus on vision but on nothing in particular. But the question still stands.
As I understand, it is not possible to be mindful of everything simultaneously. For example, you may be mindful of your vision, but doesn't that mean that at that moment you are not really mindful of your hearing?
Is there a connection between rigpa and mindfulness in this regard, where rigpa is found in the specific experience only, or is rigpa all-encompassing? I have never seen this discussed before.
I am inclined to think that rigpa is not tied to mindfulness in this way, but that would probably mean that it is possible to fall in a ditch because you did not notice it while being in rigpa.
