What is not regeneration (2)
Good intentions or love, since love needs wisdom in order to act for good purposes. Good intentions ‘mean well’, but often stray through lack of insight, even lack of common sense.
Suffering by itself is something that happens to us, not something we do. There are many causes of suffering (natural and human); what is spiritually significant is how we respond to these. (see eg Matt. 15:17-20)
Elevated, expanded, consciousness, since expanding our consciousness even to the whole universe and over all time, or making it run fast or slow, does not show us what is spiritual, let alone help us regenerate our spiritual nature.
