Janus - the god who looks both ways, turning points, guardian of doorways, is a mythological character. January is named after him. Janus...turning points. Each of us face turning points every second of every day because we get to choose everything we do. Even people who tell you they have no choice, have choices. It is remarkable how those choices create our interior lives. Remarkable how we choose how we feel. Janus and turning points mean I need to think for myself more than ever because (even though I am one person) what I do affects everyone else.
So Buddhism is right -- one action leads to another -- choose carefully -- but choose and keep moving.
