This is the true Dharma, reborn.
Culturally, we learned to see a thing as a totality. Worst, many people see a part as the group (in which this part belongs), making generalizations towards the exterior. Both these ways are wrongs ways of seeing things.
Regarding the second point, the point of making generalizations towards the exterior, for example, seeing an action of an individual and (wrongly) believing that the whole group in which this individual takes part does (or thinks) similar to what this act represents, you have the answer of following the motto “all generalizations are wrong”. In believing in your mind in this motto; and following it. Also, for completeness, you may, maybe later, make the motto be “all generalizations are wrong, including this one”.
Regarding the first point, the point of seeing a thing as a totality, for example, by injecting a human body and (wrongly) believing that the whole human body in which the injected muscle belongs, reacts with, or has, a similar (overall) effect to the medication (either everytime, either everywhere, either in everybody), you have the answer of following the motto “the one is wrong”. In believing in your mind in this motto; and following it. Also, for completeness, you may, maybe later, make the motto be “the one is wrong, including the unity / the meaning of this motto”.
