大華嚴經略策 1.23

1.23

第十六、說十之由。問：諸經之中法相隨義，三身、四智、五眼、六通，隨數減增不可一準。如何此教多說十耶？答：真理圓融非相不顯，欲彰圓妙故寄十以明之。十是一周數之圓故，多則難盡、少不顯圓。又盡理而言十方備足，故五眼開為十眼，三身具說十身，欲令觸目圓融一一皆入法界，故多說十，斯可知也。謹對。

Sixteenth: The Reason for Speaking of Ten. Question: In the various sūtras, the characteristics of dharmas follow the meaning: three bodies, four wisdoms, five eyes, six supernormal knowledges—varying by decrease and increase, they cannot be standardized. Why does this teaching mostly speak of ten? Answer: The true principle is perfectly interfused, and without characteristics it is not revealed; desiring to display the complete and wondrous, it is therefore expressed by relying on ten. Ten is the completion of a full cycle of numbers; more would be difficult to exhaust, and fewer would not reveal completeness. Moreover, speaking exhaustively of principle, the ten directions are fully complete; thus the five eyes are opened into ten eyes, and the three bodies are fully explained as ten bodies. Desiring that whatever meets the eye be perfectly interfused and that each and every one enters the dharmadhātu, it therefore mostly speaks of ten; this can be known from this. Respectfully answered.
