Meaning

But for the person who's all about that self-love, who's totally content and satisfied within themselves, there's literally nothing left to do.

Commentary

No cap, the sage is straight chillin'. They don't need no external stuff for happiness. They're totally self-satisfied, their joy and contentment is all internal. For a sage who's got that self-knowledge, it's a no-brainer; there's nothing left to do. They've already done it all, achieved all their desires, and are completely content. (II.55)
