Śrīmad-Bhāgavatam · Text 7.13.6
Who is speaking and story frame
नाभिनन्देद् ध्रुवं मृत्युमध्रुवं वास्य जीवितम् ।
कालं परं प्रतीक्षेत भूतानां प्रभवाप्ययम् ॥ ६ ॥
nābhinanded dhruvaṁ mṛtyum
adhruvaṁ vāsya jīvitam
kālaṁ paraṁ pratīkṣeta
bhūtānāṁ prabhavāpyayam
Since the material body is sure to be vanquished and the duration of one’s life is not fixed, neither death nor life is to be praised. Rather, one should observe the eternal time factor, in which the living entity manifests himself and disappears.
