verse 13

इह चेदवेदीदथ सत्यमस्ति न चेदिहावेदीन्महती विनष्टिः ।
भूतेषु भूतेषु विचित्य धीराः प्रेत्यास्माल्लोकादमृता भवन्ति ॥ १३ ॥

iha cedavedīdatha satyamasti na cedihāvedīnmahatī vinaṣṭiḥ |
bhūteṣu bhūteṣu vicitya dhīrāḥ pretyāsmāllokādamṛtā bhavanti || 13 ||

13. If one knows (That) here, then there is truth. If one knows not (That) here, there will be great loss. The wise, seeing the on e Atman in all created things, having turned away from this world, become immortal. (13)

Shankara’s Commentary:

Com:—It is, indeed, hard to suffer birth, old age, death, sickness, etc., owing to ignorance, being one of the crowd of living beings, such as Devas, men, beasts. (pretas), etc., full of the miseries of Samsara. Therefore if a man, even in this world being authorised and competent, knows the Atman as defined, in the manner already explained, then there is truth; i.e., there is in this birth as a mortal, immortality, usefulness, real existence. But if one living here and authorised does not know the Brahman, then there is long and great misery for him, i.e., rotation in Samsara—one continuous stream of births and deaths. Therefore the Brahmins who know the advantages and the disadvantages as above pointed out, perceive in all things in the universe, immoveable and moveable, the one essence of the Atman, i.e., the Brahman, turn away with disgust from this world, the creature of ignorance consisting in the false notion of ‘I’ and ‘mine’ and having realised the principle of unity, the oneness of the Atman in all, become immortal, i.e., become Brahman itself; for, the Sruti says “He who knows that highest Brahman becomes Brahman itself.”
