Some very profound documentaries to watch are Human (which comes in 3 parts), Samsara (2011/12), Baraka, Finding Joe, The Game Changers (on Netflix), I’m sure others will add. ?
Abraham Maslow's Toward a Psychology of Being, The Farther Reaches of Human Nature (Arkana), and/or his book The Hierarchy of Needs: A Theory of Human Motivation, most certainly all the books by Dr M Scott Peck. 'On becoming a person' and 'A way of being' by Carl Rogers are also extremely beneficial.
