Srimad-Bhagavatam: Canto 11 - Chapter 1 - Verse 50

Sanskrit:

तरोर्बीजविपाकाभ्यां यो विद्वाञ्जन्मसंयमौ ।तरोर्विलक्षणो द्रष्टा एवं द्रष्टा तनो: पृथक् ॥ ५० ॥

ITRANS:

taror bīja-vipākābhyāṁyo vidvāñ janma-saṁyamautaror vilakṣaṇo draṣṭāevaṁ draṣṭā tanoḥ pṛthak

Translation:

One who observes the birth of a tree from its seed and the ultimate death of the tree after maturity certainly remains a distinct observer separate from the tree. In the same way, the witness of the birth and death of the material body remains separate from it.

Purport:

As a reference to trees, vipāka indicates the final transformation called death. In reference to other types of plants such as rice, vipāka indicates the stage of maturity, in which death also occurs. Thus by common observation one can understand the actual position of one’s material body and one’s own position as the transcendental observer.
