Do you believe you have a purpose?
I suggest that first and foremost there be a radical and acute investigation into this "you" that is believed to be, rather than create drama around a locus that may not actually exist.
Certainly it may seem to be, but is it true that we are some incomplete-being that requires some additional purpose? Or is all significance found immediately present and complete within conscious Be-ing itself? I suggest taking the first step first, before jumping ahead and making a grand journey.
Perhaps what already IS, is infinitely more real and fulfilling than any purpose, or any other thing -- not present.
