四明十義書 1.115

1.115

如專觀此一珠，雖見眾珠光影，實未遍觀眾珠。以眾珠光影全在一珠之中，何須放心遍觀耶？如此則專於內心觀一切法也。

If one contemplates exclusively this single jewel, although one sees the light and reflections of all the jewels, in reality one has not yet universally contemplated all the jewels. Because the light and reflections of all the jewels are entirely within this single jewel, what need is there to let the mind loose to contemplate universally? In this manner, one contemplates all dharmas exclusively within the inner mind.
