華嚴經探玄記 18.67

18.67

初舉法勸修中，六十由旬者，古人云：修六度行故。海岸國者，此國在海濱故。天竺梵本名海岸楞伽道。解云：此國通向楞伽山故也。又到勝流法界之岸故。又前入於海門，今達到海岸故也。善往者，巧入理住。又身住虛空，行路無礙，名為善住。勸往教問，敬遶辭退，竝可知。略無歎德。

First, in citing the Dharma to exhort cultivation: "sixty yojanas" was said by past masters to be because of cultivating the practice of the six pāramitās. "The country of the Seashore": because this country is on the coast of the sea. The Indian Sanskrit manuscript gives the name "Seashore Laṅkā Path"; the explanation is that this country leads toward Mount Laṅkā. Furthermore, it is because he reaches the shore of the dharmadhātu of superior flow. Again, having previously entered the ocean gate, he now reaches the seashore. "Good Departure" (Supratiṣṭhita): skillfully entering and abiding in the principle. Furthermore, his body abides in empty space and walks the path without obstruction, hence he is named "Good Abiding" (Supratiṣṭhita). Exhorting him to go, instructing him to inquire, paying homage by circumambulating and taking leave, can all be known. Praising virtues is omitted.
