“Virtue is a strength. Concentration is a strength. Discernment is a strength.
When they pool their strengths and work together so that they’re one and the same, that’s called magga-samangi: the path in harmony. As soon as this harmony arises, that’s when you awaken to the Dhamma. It’s like all of us here. When we’re in harmony, we can be at our ease. Like students or teachers: If the teachers are in harmony, if the students are in harmony, the whole school is at ease. When the students are not in harmony and the teachers are not in harmony, running off in different directions, then there’s no peace. The teachers and students have to cooperate: teachers following their duties as teachers, students following their duties as students. Each person performs his or her duties to the full. No problems will arise.
The same with practicing concentration: When there’s virtue, concentration, and discernment, all kinds of good things will stand out right there, right where they’re helping one another in harmony.
To bring the matter in even closer, into the body: When the properties of earth, water, fire, and wind are in harmony, the body is beaming with health— because of the harmony within it. But if the body isn’t in harmony—if there’s too much fire, too much earth, and not enough wind—the body will grow sick and uncomfortable.”
