महाभारतः mahābhārataḥ - book-12, chapter-13, verse-4

द्व्यक्षरस्तु भवेन्मृत्युस्त्र्यक्षरं ब्रह्म शाश्वतम् ।
ममेति च भवेन्मृत्युर्न ममेति च शाश्वतम् ॥४॥

4. dvyakṣarastu bhavenmṛtyustryakṣaraṁ brahma śāśvatam ,
mameti ca bhavenmṛtyurna mameti ca śāśvatam.

4. dvyakṣaraḥ tu bhavet mṛtyuḥ tryakṣaraṃ brahma śāśvatam
mama iti ca bhavet mṛtyuḥ na mama iti ca śāśvatam

4. mṛtyuḥ tu dvyakṣaraḥ bhavet,
brahma śāśvatam tryakṣaram.
"mama" iti ca mṛtyuḥ bhavet,
"na mama" iti ca śāśvatam (bhavet).

4. Indeed, 'death' (mṛtyu) is two-syllabled, whereas 'Brahman' (brahman) is eternal and three-syllabled. The thought 'mine' (mama iti) truly leads to death (mṛtyu), but 'not mine' (na mama iti) leads to the eternal (brahman).
