From beginningless time up until this moment, we have cared solely for ourselves and worked solely for our own benefit. Every exertion we performed was for our own benefit alone. But by acting in this way, all we have actually accomplished is more and more suffering. So this time, instead of caring for ourselves, we must care for others.
As Shantideva said, “All the sufferings that beings experience in this universe arise from caring for oneself, and all the happiness that beings experience in this world arise from caring for others.” If we had already practiced caring for others in our previous lives, we would not still be in samsara — we would have already attained liberation and enlightenment. The cause of our not having cared for others is the natural tendency to care for ourselves. This is a very gross mistake. The way to correct it is to ignore oneself and to totally devote one’s energy and efforts to benefiting other sentient beings.
