Rev. Master Jiyu would say, “It (emptiness) is the fullest emptiness you will ever know”. She was talking from her own experience and understanding and when ever I heard her say that I thought, “well that’s good” but didn’t ‘get’ what she was saying.

Here is a quote I find rather helpful in understanding the Buddhist concept of emptiness.

I often use the example of a hand in speaking about emptiness; we can call it a hand or we can call it a collection of five fingers. As a collection of five fingers, each finger is independent and has a different shap and function. We cannot exhange the little finger with the thumb because each has its own function, shape, and unique way of being. A thumb cannot do precisely what a little finger does and a little finger cannot do what a thumb does. Each finger is truly independent. And yet, from another perspective as one hand, all five fingers function together, and there is no separation between them. When we see the fingers in this united way, there is really just one hand
