None of these cause ‘enlightenment,’ either individually or simultaneously.

‘Enlightenment’ is not an event, practice or attainment that happens in time to and ‘individual.’ Absolutely not.

The mind can’t get this, because mind is synonymous with time, cause-&-effect and subject-object - “I” [subject] know or experience this [object]

Enlightenment is already present. and you will ‘know’ this (more accurately, Be this) when “you” finally let go of all causes, effects, concepts of ‘enlightenment,’ and the non-existent “you” these thing could ‘happen to.’
