瑜伽師地論略纂 2.115

2.115

「又離貪瞋痴，名常樂」者，此皆斷界，離三所得，無為為性，非是斷三無漏受樂，體通伏斷，所得無為。

Regarding "Moreover, freedom from greed, hatred, and delusion is called constant bliss," these are all the realm of cessation, attained through freedom from the three, having the unconditioned as their nature; they are not the uncontaminated pleasant feeling of severing the three. Their nature encompasses both suppression and severance, being the unconditioned that is attained.
