... like my late father, Leon.
When ordinarily preparing ingredients, do not regard them with ordinary [deluded] eyes, or think of them with ordinary emotions. "Lifting a single blade of grass builds a shrine; entering a single mote of dust turns the great wheel of the dharma." Even when, for example, one makes a soup of the crudest greens, one should not give rise to a mind that loathes it or takes it lightly; and even when one makes a soup of the finest cream, one should not give rise to a mind that feels glad and rejoices in it. If one is at the outset free from preferences, how could one have any aversions? Even when confronted with poor ingredients, there is no negligence whatsoever; even when faced with scanty ingredients, one exerts oneself. Do not change your mind in accordance with things. Whoever changes his mind in accordance with things, or revises his words to suit the person [he is speaking to], is not a man of the way.
