The works of Ādi Śaṅkarācārya

Bṛhadāraṇyakopaniṣadbhāṣyam

Verse 197

यद्वृक्षो वृक्णो रोहति मूलान्नवतरःपुनः ।मर्त्यः स्विन्मृत्युना वृक्णः कस्मा-न्मूलात्प्ररोहति ॥ ४ ॥

In plain words

A felled tree grows back, fresher, from its own root. But a person cut down by death -- from what root could he ever spring up again?

Close to the Sanskrit

As a tree, when felled, grows again fresher from the root -- a mortal, when felled by death, from what root does he sprout forth again?
