Human nature is neither inherently good nor evil; good and evil are merely states of the mind (manifestations), much like day and night. The initial state of the human mind at creation is good, meaning it contains a certain amount of love, as no one is born with hatred. However, goodness is not the essence of human nature; it is merely a state. The quantity of love in the mind fluctuates with experiences and interactions with others or the environment, increasing or decreasing. When it decreases to a negative value, it turns into hatred, manifesting as evil. For example, if a person is hurt in love or friendship, their love may diminish and even potentially turn into hatred. If represented on a number line, with the vertical axis indicating the quantity of love (positive values for love, negative values for hatred) and the horizontal axis representing time, it would form a fluctuating curve.
A realization may not necessarily be correct.
