Anyway, thank you!
So, here they come:
The suffering of samsara is horrible.
Actually understanding what the term "rig pa" means is important for those who wish to end their suffering, since all Dharma paths, both Hindu and Buddhist, define the cause of suffering as ignorance (avidyā, ma rig pa) and the cause of liberation as knowledge (vidyā, rig pa).
Understanding the distinction between Mahāmudra and Dzogchen is important for those who wish to follow one path versus the other, for whatever their personal reasons may be. For others the distinction may not be important.
In the grand scheme of things there is almost nothing one can do to stem the suffering of others in samsara. Not even Buddha can remove the suffering of others. However, one can remove one's own suffering. And for this reason these sorts of conversations, in the grand scheme of things, are critically important.
Yes, rig pa can be called "recognizing the nature the mind". You always have "the nature of mind".
Of course, there are Dzogchen teachings which criticize this approach however, because it is held that buddhahood cannot be found in the mind.
So calling rig pa "the recognition of the nature of the mind" is quite provisional.
