“Asked “What is Buddha?” Ma-tsu replied “This very mind, this is Buddha.””
Now. This. Here. It’s gone, so don’t think about that. It’s coming up, don’t worry about it yet. All of these are thoughts. These thoughts are happening now. They are like drops in a still pond. Ripples. Quiet the ripples, re-still the pond, just sit. Now live.
Live and be mindful of every moment. It’s that simple. This is Buddha-mind. Screw multi-tasking, it’s not effective. It’s like circuit-training, mediocre results for cardio and anaerobic exercise. Instead do each one separately and do them well. With focus and mindfulness.
