4.232

若於此處此時此事，欲入諸定等者，泰云：所依身名處云云。基云：身所住依名處，起定明暗等時節等名時，隨緣何境名事。

Regarding "If in this place, at this time, in this matter, one wishes to enter the various meditations, etc.": Tai says: "The body that is the basis is called 'place', etc." Ji says: "The basis in which the body abides is called 'place'; the periods such as light or darkness when giving rise to meditation are called 'time'; whatever object one conditions according to the occasion is called 'matter'."
