When I started out on my spiritual journey years ago, I became very fascinated by the idea of enlightenment. To me, it represented the whole aim of life — a sentiment that I, more or less, still carry today.
And one of the very first stops on my spiritual path led me to Buddhism, and particularly Zen Buddhism.
I remember reading several books on it, practicing Zazen meditation, and incorporating mindfulness in all that I was doing — whether that was talking, eating, or breathing.
