One way that he describes this kind of state of mind, it's a state of mind, Samādhi, mind, mind of Samādhi, of concentration, which is ready, receptive, free from hindrances, elated, and confident. So to be able to kind of settle the mind, classic language - tame the mind, develop the mind, strengthen the mind. So that it's not just jumping around and running around this thought and that thought, that concern and this concerned, jumping around paying attention to all kinds of data on the environment. But to really kind of settle and gather itself together, be gathered, unified mind. So that's ready, receptive, free of hindrances. Hindrances are these forces in the mind that grab the attention so much, they're kind of like black holes. We can fall into these hindrances, like desire and Ill will, like light goes into a black hole and it doesn't see the light doesn't come out. So sometimes attention falls into the black hole of the hindrances and it doesn't come out for a while. And so to be free of hindrances is to have the attention available, really available to be present here. And then elated. This idea there's happiness and joy and well being in this inner life of ours that comes from letting go. Really a deep settling in. And the art of letting go is challenging because there's so many things we think are so important, that's we have to be concerned with things or have things be a certain way or we have to stay close to our resentments or something. But to have the confidence and trust to let go, at least in meditation. Or take the risk to just let go of all things except really be here, gathered together, settled, present.
