Hi Mary! Such a great question you ask!
I am thinking that the future unfolds according to my (and our) choices in the present. The more conscious those choices, the more it is my/our conscious self that determines the “future”. Otherwise, these seeds just sprout according to karma (conditioning) and lead to wherever karma goes.
But your question doesn’t come from a vacuum and I would love to know what observations have led you to it, if you’d like to share.
