शरीरस्थितिशैथिल्यं श्वेतलोमसमन्वितम् ।जरा भवति सा नास्ति निरंशे मयि सर्वगे ॥ ६५ ॥
In plain words
The body's firmness going slack, the hair turning white — that is what is called old age. It is not in me. I have no parts, and I am everywhere.
Close to the Sanskrit
The slackening of the body's stable condition, accompanied by white hair — that becomes old age; that is not in me, the partless, the all-pervading.
