Hi,
Shashank Dixit:
I am not sure but could it be such that the result of sincerity development be the same as the suppression of the 5 hindrances post 4rth samtha jhana so as to be conducive for further investigation ?
Yes, that is one way of looking at it; though that is the case all the time (and not just post 4th samatha jhana).
There are many discourses and categories regarding ignorance (ignorance of stress, ignorance of the cessation of stress, specific instances of ignorance, etc.). In the context of a functional view of dependent origination, all forms of ignorance are placed under one umbrella (the 'self'). Ignorance in this case then can be generally thought of as the cumulative identifications (beliefs, world-views, etc.) of a self which are confused with actuality / thought to be part of nibbana / not properly understood to be fabricated by 'me'.
To be naive is to be honest about one's self / one's ignorance / one's fabrications (and the results / kamma of those fabrications) with the pure intent to sincerely dismiss those artificial creations upon recognizing them. It is a general way of orienting one's self in the world as it is happening right now. It is a cultivated quality of being which results in the release of ignorance as a whole (and in the same way that it is a release of ignorance when applied to a single instance of ignorance, such as a belief about one's view of the world). Said another way: it is the tool that both sees ignorance and eradicates it. And so, the application of such often leads spontaneously to the experiencing of pure consciousness, as (to borrow a phrase) it is the closest a self can get to innocence. Said another way: it is like a pathway to the doorstep of the actual world.
Shashank Dixit:
It increasingly appears that the end result in both cases the same - ending of suffering, but due to the conditioning before ( sincerity in actualism practice and equanimity in insight practice ) there could be a difference in qualia of the ensuing experience.
I will need you to define your use of 'equanimity' here for me to reply.
Shashank Dixit:
But again , I am not 100% sure on anything yet and more field testing is required. I wonder how much of it I'll do though in front of the pull of a PCE

Haha, sounds good; field testing is the way to being 100% sure on anything at all.
Do you see how naivete may also lead to wonder?
