I made this diagram a while back which demonstrates how this purity of the actual trickles down into ‘my’ experience - Depictions of Pure intent
‘Reality’ is far far removed from purity, as children we are more naive so reality is not so concrete yet and so purity pokes through more.
As adults though the conditioning is very much set and initially the closest approximation to this purity may be sincerity, as in ‘I know there is more to life than this’ and ‘I’ set a sincere intent to locate it.
Then ‘I’ have a good reason to allow felicity and innocuity, and even in this feeling good ‘I’ can begin to notice a flavour of the purity that ‘I’ deep down know from somewhere.
