Question about Vijnana and the correct view of Nama and Rupa
The mind can only become aware of the mind in a subsequent moment. We get angry, and then know so. In moment 1, vinyana arises along with anger and delusion, aware only of the story. In moment 2, for a mindfulness practitioner, the vinyana arises with mindfulness and samadhi, abandoning the anger, unbonded to thought. 
In the infinite consciousness jhana there is only vinyana in its  unbonded state (bare and separate awareness). In the next moment, it is aware of itself from the previous moment. In the next moment it is aware if itself again. It is infinite it the moment to moment unended reflection, not the sense of its size.  Hope that helps!  Oh and yes there are tiny spaces of nothing between angry and mindful of it, but those are very hard to see. Once you can, you are well into vipassana, seeing there is no continuity or prevailing consciouness (anatta).
