The opportunity or ability to make a selection from a number of alternative options. The area of choice metaphysically, is how one orders their existence. It is whether a person gives priority to spirit or to matter. This is the nature of the human problem.
The humanist and metaphysically inclined should always help those who come to them wherever and whenever possible. If help cannot be given, leave them, for it is their opportunity to find themselves. If you fail, feel sad for them. If you succeed, express gratitude for the chance to serve.
