Within us and around us there is an invisible world; this is where each of us comes from... When you cross over from the invisible into this physical world, you bring with you a sense of belonging to the invisible that you can never lose or finally cancel... When you enter the world, you come to live on the threshold between the visible and the invisible... Because the invisible cannot be seen or glimpsed with the human eye, it belongs largely to the unknown. Still there are occasional moments when the invisible seems to become faintly perceptible... Now you belong fully neither to the visible nor to the invisible. This is precisely what kindles and rekindles all your longing and your hunger to belong. You are both artist and pilgrim of the threshold.
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.
