Learning to sit and experience 'sitting' (and that only)
Learning to breathe and being aware
...taking the breath, feeling it in each part of the body
learning dissolution (that happens on its own), so 'experiencing dissolution' would be more apt
Permeating the body with this feeling of lightness, breaking down
Opening up the pores, clearing the tension, more flexible (at least until u build more tension, and tirelessly work on it again ... so much so that deep-rooted habit patterns in the mind start changing, you start changing towards fear, plight, all those things)
making deliberation to be more relaxed, clear aware, more concentrated
fresh waves of dissolution, even finer
Learning to open the eyes
Coming back to real dimension where hands move and follow physical rules (of course 'as intended' by the 'mind :), where there is solidity and one gets burns if one touches hot oil
Learning to balance
You sit straight, learn to sit, stand, walk again, with balance, more upright, healthier!
But all this is not wonderful. The most significant learning is to experience with Right View (experiencing non-self). real change happens when you do that, experience fully, you will know these moments for these are like none other:)
Hint: detachment is a very powerful and natural outcome in such moments
Right View is under: 4. Phase of Cultivation
