Just to be clear I am representing a synthesis of sutta, commentary (as far as the visuddhimagga goes) and experience in my replies, and not the abhidhamma (because it doesn't sit well with the other 3 in my experience)
Being able to discern gross mental events and physical events is something most people can do. It is not something which requires citta visuddhi, the preceeding step. A mind free from hindrances is required to see paramatta dhammas. If paramatta dhammas are not seen in the first two insight knowledges there is no place further down then where causality will be discerned. To discern the paticcasamuppada for example paramatta dhammas will need to be seen (phassa --> vedana)
Eg: sound+ear gives rise to ear consciousness; these three gives rise phassa/contact and so on. To say that this means the mind door processes are faster is not meaningful at the level of experience- all nama or rupa events seem to happen at the same speed. It does however mean that more mental events follow fewer material events- or that the world is mostly
mind produced. A speed cannot be determined by it. Then again the Buddha does speak of the mind changing faster than the body in the suttas. This can be understood at a mundane level where things are seen to change quicker and last less longer. Actual numbers (ie speeds) were never mentioned in the suttas and are not conducive to those who wish to experience the teachings for oneself.
See below: the Buddha guides a monk to insight. Note that he is using the five aggregates- elements of ultimate reality, nama and rupa. I believe this type of conversation reflects a summary of what the monk has already experienced through vipassana, needing that final summary and 'push' to form all the links clearly in his mind, leading to insight.
"What do you think, monks — Is form constant or inconstant?"
"And is that which is inconstant easeful or stressful?"
"And is it fitting to regard what is inconstant, stressful, subject to change as: 'This is mine. This is my self. This is what I am'?"
"...Is feeling constant or inconstant?"
"...Is perception constant or inconstant?"
"...Are fabrications constant or inconstant?"
"What do you think, monks — Is consciousness constant or inconstant?"
"Thus, monks, any form
whatsoever that is past, future, or present; internal or external; blatant or subtle; common or sublime; far or near: every form is to be seen as it actually is with right discernment as: 'This is not mine. This is not my self. This is not what I am.'http://www.accesstoinsight.org/tipitaka ... .than.html
--when he says ANY form, he is confirming the third insight knowledge sammassana nana - that ALL things follow in this pattern.
"Friend, how many conditions are there for the arising of right view?"
"Friend, there are two conditions for the arising of right view: the voice of another and appropriate attention. These are the two conditions for the arising of right view."
"And assisted by how many factors does right view have awareness-release as its fruit & reward, and discernment-release as its fruit & reward?"
"Assisted by five factors, right view has awareness-release as its fruit & reward, and discernment-release as its fruit & reward. There is the case where right view is assisted by virtue, assisted by learning, assisted by discussion, assisted by tranquility, assisted by insight. Assisted by these five factors, right view has awareness-release as its fruit & reward, and discernment-release as its fruit & reward."http://www.accesstoinsight.org/tipitaka ... .than.html
Right speech, right action, & right livelihood come under the aggregate of virtue. Right effort, right mindfulness, & right concentration come under the aggregate of concentration. Right view & right resolve come under the aggregate of discernment."http://www.accesstoinsight.org/tipitaka ... .than.html
--As can be seen right view does come under panna, but is at a more verbal level. I would hesitate to call it superficial as there is supramundane right view as well- the view of the stream entrants and those higher in the path.
