जन्मवृद्धिपरिणत्यपक्षय -व्याधिनाशनविहीनमव्ययम् ।विश्वसृष्ट्यवनघातकारणंब्रह्म तत्त्वमसि भावयात्मनि ॥ २५९ ॥
In plain words
It is never born, never grows, never changes shape, never decays, is never sick, and never dies — utterly undiminished. And yet it is the very cause behind this universe coming into being, being sustained, and passing away. That is Brahman. And that is you. Hold it within.
Close to the Sanskrit
That which is devoid of birth, growth, transformation, decay, disease, and destruction; imperishable; the cause of the creation, preservation, and destruction of the universe — that Brahman [is]: thou art That; contemplate [this] within yourself.
