Daily sitting is our bread and butter, the basic stuff of dharma. Without it we tend to be confused.
Joy is being willing for things to be as they are. 
Joy is being the circumstances of our life just as they are. 
At any given moment, we are the way we are, and we see what we're able to see. 
Though for short periods it seems to be distinguishable as a separate event, the water in the whirlpools is just the river itself. 
If we can accept things just the way they are, we're not going to be greatly upset by anything. 
Living Zen is nothing special: life as it is. Zen is life itself, nothing added.
