The Buddhas of the ten directions are compassionately mindful of living beings just as a mother remembers her child. But if the child runs away, of what use is the mother's concern? However, if the child remembers the mother in the same way that the mother remembers the child, then in life after life, mother and child will never be far apart. If living beings remember the Buddha and are mindful of the Buddha, they will certainly see the Buddha now and in the future. Being close to the Buddha even without special assistance, they will awaken by themselves.
