28.26

此即所味著者，此淨等至是前味定所味著境，謂淨定滅，彼味定生，緣已滅淨，深生愛著。

Regarding "This is what is relished": this pure attainment is the objective domain relished by the preceding tainted concentration. That is, when the pure concentration ceases, that tainted concentration arises, taking the ceased pure [concentration] as its object and giving rise to deep attachment.
