“Four abode” of mind refer to the four meditative stabilizations. It means the training of mind, which is “blissful” because the mind abides blissfully in the lifetime.
Master Ri-Chang describes it:
这四样东西─四禅,通常我们也叫作“离生喜乐、定生喜乐、离喜妙乐、舍念清净地”。
And finally, 观 or 慧学:
【四谓四谛,各四行者,】
The four (where the Sūtra requested by brahma reads “the four aspects of the four”) are the four (noble) truths. The four aspects of these four are the four aspects of each of the four truths.
【苦中无常苦空无我,】
For the truth of suffering: impermanent, suffering, empty, and selfless;
【集中因集生缘,】
For the truth of the origin: cause, origin, arising, and condition;
【灭中灭静妙离,】
For the truth of cessation: cessation, pacification, excellence, and freedom
【道中道如行出,】
For the truth of the path: path correctness, achievement, and deliverance.
