If you fall into poverty, live that way without grumbling - then your poverty will not burden you. Likewise, if you are rich, live with your riches. All this is the functioning of Buddha-nature. In short, Buddha-nature has the quality of infinite adaptability.
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 KapleauThe 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 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 KapleauUltimately the case for shunning animal flesh does not rest on what the Buddha allegedly said or didn't say. What is does rest on is our innate moral goodness, compassion, and pity which, when liberated, lead us to value all forms of life. It is obvious, then, that willfully to take life, or through the eating of meat indirectly to cause others to kill, runs counter to the deepest instincts of human beings.
