Young souls look to secrets, rites, and rituals
Advanced souls look to science, math, and evidence
And old souls... old souls look within.
Anyhow, the one thing I know for sure is that with time, and by looking within, everything becomes clear, all questions are answered, what's broken is restored, new trails are blazed, hearts are mended, love returns, and you will look over your shoulder at life's utter perfection with a tear in your eye.
And best of all, time is one thing we souls have plenty of.
