"Ratnākara, the various kinds of living beings are in themselves the Buddha lands (buddhakṣetra) of the bodhisattva. Why so? Because it is by converting various beings to the teachings that the bodhisattvas acquire their Buddha lands. It is by persuading various beings and overcoming their objections that the bodhisattvas acquire their Buddha lands. It is by inducing the various living beings to enter into the Buddha wisdom in such-and-such a land that they acquire their Buddha lands. It is by inducing the various living beings to develop the capacity for bodhisattva practices in such-and-such a land that they acquire their Buddha lands. Why is this? Because the bodhisattva's acquisition of a pure land is wholly due to his having brought benefit to living beings. Suppose a man proposes to build a mansion on a plot of open land. He may do so as he wishes without hindrance. But if he tries to build it in the empty air, he will never be successful. It is the same with the bodhisattvas. It is because they wish to help others to achieve success that they take their vow to acquire Buddha lands. Their vow to acquire Buddha lands in not founded on emptiness."
