【十寶】《光明》云：「我當安止住於十地，十種珍寶以為脚足。」天台釋云：珍寶者，十地因可貴，諸地即是珍寶也。脚足者，十地是果家之基，故言脚足。又十度，是十地之脚足。於餘功德，非為不修，隨力隨分。正以檀為初地之足，檀足若滿，得入初地，乃至智度足滿，得入十地。又如《法華》十喻況勝，文見彼經。

[Ten Jewels] The Suvarṇaprabhāsa-sūtra says: 'I shall peacefully abide in the ten grounds, with ten kinds of precious jewels as feet.' Tiantai explains: As for precious jewels, the causes of the ten grounds are precious, and the various grounds are themselves precious jewels. As for feet, the ten grounds are the foundation of the house of fruition, hence called feet. Furthermore, the ten pāramitās are the feet of the ten grounds. Regarding the remaining merits, it is not that one does not cultivate them, but does so according to one's capacity and measure. Dāna is properly the foot of the first ground; when the foot of dāna is complete, one attains entry into the first ground, and so on up to when the foot of the perfection of wisdom is complete, one attains entry into the tenth ground. Also, like the ten similes of the Lotus Sūtra illustrating superiority, the text appears in that sūtra.
