Developing a deep quality of interest is one of the keys to the whole art of concentration. Our steadiness is nourished by the degree of interest with which we focus our meditation ... Concentration combines full interest with a delicacy of attention. This attention should not be confused with being removed or detached. Awareness does not mean separating ourselves from experience; it means allowing it and sensing it fully ... As we learn to steady the quality of our attention, it is accompanied by a deeper and deeper sense of stillness -- poised, exquisite and subtle.
