ब्रह्मानन्दजलेनैव लोकाः सर्वे परिप्लुताः ।अच्छेद्योऽयमिति ध्यानमभिषेचनमात्मनः ॥ १४ ॥
In plain words
One water floods every world there is — the bliss that is Brahman, and nothing else poured. To hold this steadily in mind — this cannot be cut — that is the bathing of the Self.
Close to the Sanskrit
By the water of Brahman-bliss alone are all the worlds flooded over; the meditation 'this is uncleavable' is the ceremonial bathing of the Self.
