I ‘believe’ volition, intention, is involved in why there is a change of posture - from standing to sitting. However, what happens once the process of natural stillness starts to deepen?
It’s not unlike the growth and development of a seedling. A seedling will develop into a plant if it grows in the right soil, has enough water and sunlight etc.
The growth of the seedling has nothing to do with it ‘intending’ to grow. There’s no volition that arises in the ‘mind’ of a seedling.
Likewise, with calming and settling into deep stillness. If the right conditions are present there is nothing that can be ‘done’ by the meditator to prevent it from happening.
It happens by itself when the sense of a doer dissolves, is lost to the beauty. The meditating subject dissappears, it simply vanishes.
I don’t want to give the impression that this vanishing is something humdrum and commonplace. It’s not like quietly dozing-off when we go to sleep.
When immersion ends, it’s not like waking up in the morning. After samadhi it’s not like waking up after a good night’s sleep.
The vanishing of subjectivity is abrupt. There is literally no subjectivity, no awareness of a physical body - no edge, no outline and, nothing inside the physical body, no sensory contact. Those forms of consciousness and, perceptions have completely ceased without trace.
It’s a radical departure from the known and when the sense of self returns it soon becomes clear that something very different from normality has taken place.
This happening inevitably tells you something about your normal state that you had always taken for granted. It ‘was’ just a given i.e. I am - the sense of being someone is not something fundamental and inescapable. It’s possible to imagine not being somebody but this, is not a product of the imagination.
It’s ‘actually’ a completely new discovery, as if, we had been living under water all our life and suddenly there is the discovery of the atmosphere, dry land, the world we live in.
If this is not a radical insight I don’t know what else you could call it?
