Day One Hundred and Twenty Eight

Working from http://www.paauk.org/files/knowing_and_seeing_rev_ed.pdf :

When a material object strikes upon its material door, a cognitive process of the first five doors arises: this is called a five - door cognitive process (pañca dvāra vīthi) . But a cognitive process of the sixth door, the mind - door (the bhavaïga), is called a mind - door cognitive process (mano dvāra vīthi) . As also mentioned before, when one of the five types of material object strikes upon its material door, it strikes at the same time upon the mind door (bhavaïga):
When discerning mentality, you first discern the different types of cognitive process, which means you discern how many consciousness moments (cittakkhaõa) there are in each cognitive process, and discern the different types of consciousness moment.

and from page 117 and 213, to look for this that happens:

1. Five-door cognitive process that ‘picks-up’ the object; in the case of the eye and a colour object, it cognizes only that there is colour.
2. Mind-door cognitive process that perceives the colour; compares the present colour with a past colour; knows the past colour.
3. —"— —"— knows which colour it is; knows the colour’s name.
4. —"— —"— knows the ‘meaning’ of the object; sees the whole image, a concept, determined by past experience (perception (saññā)).
5. Mind-door cognitive process that judges and feels. This is the beginning of true cognition, when mental proliferation takes place (papañca) and kamma is performed, as we perceive the object to be permanent (nicca), happiness (sukha), and self (atta). (The Vipassanā mind-door cognitive process sees the object as impermanent (anicca), suffering (dukkha), and non-self (anatta)).
6. With this same object arise countless cognitive-processes (mental formations (saïkhārā)), re-inforcing the cognition.
