The door to all suffering comes from the self-cherishing thought, only thinking of our own happiness, Rinpoche warns. This not only harms us, but also harms numberless sentient beings now, has harmed them in the past from beginningless rebirths, and will harm them in the future. Conversely, cherishing others, changing our mind into bodhicitta, opens the door to all happiness up to enlightenment. The purpose of life is to benefit others, not to use them for our own pleasure. A selfish mind brings many problems, so we must let go of the I and cherish others. Rinpoche emphasizes that by cherishing even one sentient being, we can achieve enlightenment. The teaching for this episode was recorded on November 10, 2018, at Nagarjuna C E T Madrid, Spain.
