法華文句記 2.101

2.101

約觀解者，三教觀行猶如行旋，皆成圓觀猶如念佛。又觀秖是念，以觀轉故，故云增也。「若觀」下寄觀以論本迹。若約體用及久近者，本住非動非不動之法身，迹示諸教機動繞佛。

In terms of the contemplative explanation: the contemplative practices of the three teachings are like circumambulating; they all become the perfect contemplation, like recollecting the Buddha. Furthermore, contemplation is simply recollection; because contemplation is transformed, it is said to increase. From "if contemplating..." onward, it draws on contemplation to discuss origin and traces. If in terms of essence and function, and the remote past and recent: the origin resides in the dharmakāya that is neither moving nor unmoving; the traces manifest the capacities of the various teachings stirring and circumambulating the Buddha.
