This is again due to the deluded sense of separateness that we all suffer under. This sense of separate self-hood is the fundamental prejudice and the feelings of being threatened and the need for defensiveness and oppression that follows in its wake cause untold misery in this world. The more we can undermine this prejudice separateness, the more we will be able to tolerate difference and disagreement. The more tolerant we become, the more peaceful will be our immediate world and eventually the wider world. In order to undermine our delusion of separate self-hood, we need to hear the Dharma and to reflect on the Dharma and allow it to change us. In other words, we need to be receptive to the Dharma.
