In the second liberation, both substance and category are liberated, hence it is called "external." Ji says: Ancient masters said, "Internally having the notion of form, one contemplates external form." This designation is inaccurate, because "having form" is not merely internal, and the forms contemplated are not merely external. Now, based on the Xianyang [lun], "possessing the notion of form" means mental engagement through resolution relying on meditation with form; "forms" means contemplating internal and external forms.
