ध्यातव्याभावविज्ञानं निदिध्यासनमात्मनः ।समस्तभ्रान्तिविक्षेपराहित्येनात्मनिष्ठता ॥ ३० ॥
In plain words
To realize that there is nothing left to meditate on — that is the Self's own nididhyāsana. With every delusion's scattering gone, there is only abiding as the Self.
Close to the Sanskrit
The realization of the absence of anything to be meditated upon is the nididhyāsana of the Self; through the total absence of all delusion's scattering, there is abidance in the Self.
