I am talking about what we think and how we act. If these two things can go together, then meditation begins. To not bring about this dichotomy in one’s life, one has to be eternally watchful.
It means, as you go about your life, a part of your mind should carefully watch your thoughts and action. This eternal vigilance, I think, is a better form of meditation than sitting cross-legged for an hour and falling into a semi-sleep.
