The uniqueness of zazen lies in this: that the mind is freed from bondage to all thought forms, visions, objects, and imaginings, however sacred or elevating, and brought to a state of absolute emptiness, from which alone it may one day perceive its own true nature, or the nature of the universe.
Philip KapleauMindfulness is a state wherein one is totally aware in any situation and so always able to respond appropriately. Yet one is aware of being aware. Mindlessness, on the other hand, or "no-mindness" as it has been called, is a condition of such complete absorption that there is not vestige of self-awareness.
Philip KapleauFor the ordinary man, whose mind is a checkerboard of crisscrossing reflections, opinions, and prejudices, bare attention is virtually impossible; his life is thus centered not in reality itself but in his ideas of it. By focusing the mind wholly on each objects and every action, zazen strips it of extraneous thoughts and allows us to enter into a full rapport with life.
Philip KapleauAnyone familiar with the numerous accounts of the Buddha's extraordinary compassion and reverence for living beings - for example his insistence that his monks strain the water they drink lest they inadvertently cause the death of any micro-organisms - could never believe that he would be indifferent to the sufferings of domestic animals caused by their slaughter of food
Philip KapleauTo suppress the grief, the pain, is to condemn oneself to a living death. Living fully means feeling fully; it means becoming completely one with what you are experiencing and not holding it at arm's length.
