निर्विचार-वैशारद्येऽध्यात्मप्रसादः ॥

nirvicāra-vaiśāradye'dhyātmaprasādaḥ

The concentration "without discrimination" being purified, the Chitta becomes firmly fixed.

In plain words: When the highest of these meditations becomes pure, the mind (chitta) becomes steady and firmly settled. Inner clarity follows.
