Mindfulness 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 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 KapleauEvery individual who eats flesh food, whether an animal is killed expressely for him or not, is supporting the trade of slaughtering and contributing to the violent deaths of harmless animals.
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.
