4.35

As for 'seeing the buddhas of the ten directions belongs to the śrāvakas', this corresponds to the sūtra's 'seeing buddhas in the pores'. Question: The Hīnayāna does not speak of buddhas of the ten directions; why does it say that seeing the buddhas of the ten directions belongs to the śrāvakas? Answer: Among the Hīnayāna, the various schools differ; there are also those who believe in the buddhas of the ten directions. That is, Hīnayāna practitioners cultivating the fourth dhyāna see the buddhas of the ten directions through the power of the concentration of the ultimate limit, and so forth.
