[This] analogy is concerned with two kinds of gems P’o-1i (a crystal) and Ju-i (wish-granting gem). Although both are called gem, the former as a crystal cannot rain down treasures, which analogizes emptiness (that is one-sided view). For Chih-i, one-sided emptiness refers to the attainment of the śrāvaka who is only concerned about the salvation of himself, but not of others; and the treasure refers to the bodhisattva practice of helping others. Since emptiness does not involve the functional aspect of saving living beings, the gem P’o-1i that cannot rain down treasures is taken to analogize emptiness. The wish-granting gem, on the other hand, analogizes the Middle Way. Since the Middle Way signifies the comprehensive view of affirming both emptiness and the provisional existence, it involves the bodhisattva’s actions of saving living beings in the phenomenal world. Therefore, the gem Ju-i that can rain down treasures is taken to analogize the functional nature of the Middle Way. From the practical dimension, this analogy is meant to say that the substance of the Lotus Sūtra is synonymous to the wish-granting gem Ju-i, which is dynamic, functional, and impartial.
