Some quotes that stuck out in my reading today from Sekida's translation of Mumonkan:
"But when your mind attaches itself and makes a problem of what there is or is not, then the feeling comes of being a victim of events, of falling under the yoke of causation. A child does not feel such a yoke. He simply lives life as it happens and enjoys it because he lives in samadhi."
"Man is absorbed in his own actions in the moment of sitting down, standing up, taking a step, opening a door, or raising his hand or finger. But is he really acting in a state of true samadhi? True samadhi controls not only momentary attention but also the whole stream of consciousness: that is, the trend of the mind."
"There is a crucial moment in one's life when determination decides one's destiny."
