"The only measure on this path is our level of equanimity and awareness" - S.N. Goenka
But I've also read that insight needs to happen and firstname.lastname@example.org has 7 stages of realisations.
How do we know we are on the right path (for cessation of suffering) ? What if we spend 50 years and have gotten no closer to the goal.
I feel both of the above go with each other, we need equanimity and awareness and this should increase. BUT I feel you still need insights I to the nature of things.
I read a Therevada list of stages of realisations, I think they have like 20 of them. Don't remember where I read it.
My definition of insight is a clear experience that does not include an intellectual understanding. It is in relation to how we perceive reality.
