I like the way this presentation uses the word ‘knowing’ to point to our underlying condition. This usage is clearly separated from everyday knowledge of or about (something), or even of wisdom and understanding. It also avoids the term ‘consciousness’, which tends to invite metaphysical and scientific debates that lead us away from direct experience. ‘Awareness’ is a noun and so seems like a thing – we don’t generally talk about ‘awareing’. I personally like ‘being’ as an alternative, but it carries philosophical baggage and is not specific enough for the context of this presentation. Current usages within the Western Way of the term ‘gnosis’ do not generally reflect the view discussed here.
It may be true, as the Tao Te Ching says, that the Way that can be named is not the real Way. But we still need language, as a pointer, for that in us which needs to make sense of experience and to share it with others. Here, a skilful choice of words can make a difference, and I think this presentation models the skill. Dzogchen is a tradition within Tibetan Buddhism. ‘Rigpa’ is the Tibetan word used to describe ‘knowing’ in this sense.
