It’s something we can all ‘do’…
..and it’s based on reasoning
Enlightenment is awareness of absolute clarity of the mind, free of contamination, resulting in pure awareness. Realising that ideas of self and phenomena (contaminates) are made up of parts and therefore have no solid, inherent existence, our grasping and attachment to these illusions drops away.
As a result, our habitual behaviour (karma/contaminates) softens and dissolves. When our habitual behaviour completely dissolves, enlightenment naturally occurs. It makes sense.
We don’t need to do anything but recognise,
neither accepting nor rejecting contaminates
as that involves ‘doing’.
All we need is a good atmosphere.
The Buddha’s teachings make sense.
