। ॥ ४११ ॥
In plain words
In samādhi, the wise one feels, right there in the heart, the whole of Brahman — untouched by age, untouched by death, its true nature clear of every false appearance, still as a vast, motionless expanse of water, with no name that could ever fit it, every quality and modification stilled, eternal, wholly at peace, one without a second.
Close to the Sanskrit
In samādhi, the wise one perceives in the heart the full Brahman — unaging, deathless, whose true nature has set aside every illusory appearance, resembling a still mass of water, without a name, whose modifications of quality are stilled, eternal, peaceful, one.
