śrī-bhagavān uvāca
aśocyān anvaśocas tvaḿ
prajñā-vādāḿś ca bhāṣase
gatāsūn agatāsūḿś ca
nānuśocanti paṇḍitāḥ

Translation

The Supreme Personality of Godhead said: While speaking learned words, you are mourning for what is not worthy of grief. Those who are wise lament neither for the living nor for the dead.

na tv evāhaḿ jātu nāsaḿ
na tvaḿ neme janādhipāḥ
na caiva na bhaviṣyāmaḥ
sarve vayam ataḥ param

Translation

Never was there a time when I did not exist, nor you, nor all these kings; nor in the future shall any of us cease to be.

dehino ‘smin yathā dehe
kaumāraḿ yauvanaḿ jarā
tathā dehāntara-prāptir
dhīras tatra na muhyati

Translation

As the embodied soul continuously passes, in this body, from boyhood to youth to old age, the soul similarly passes into another body at death. A sober person is not bewildered by such a change.

mātrā-sparśās tu kaunteya
śītoṣṇa-sukha-duḥkha-dāḥ
āgamāpāyino ‘nityās
tāḿs titikṣasva bhārata

Translation

O son of Kunti, the nonpermanent appearance of happiness and distress, and their disappearance in due course, are like the appearance and disappearance of winter and summer seasons. They arise from sense perception, O scion of Bharata, and one must learn to tolerate them without being disturbed.

yam hi na vyathayanty ete
purusham purusharsabha
sama-duhkha-sukham dhiram
so ’mrtatvaya kalpate

 Translation of Bhagavad Gita 2.15

O best among men [Arjuna], the person who is not disturbed by happiness and distress and is steady in both is certainly eligible for liberation.

nāsato vidyate bhāvo
nābhāvo vidyate sataḥ
ubhayor api dṛṣṭo ‘ntas
tv anayos tattva-darśibhiḥ

Translation

Those who are seers of the truth have concluded that of the nonexistent [the material body] there is no endurance and of the eternal [the soul] there is no change. This they have concluded by studying the nature of both.

avināśi tu tad viddhi
yena sarvam idaḿ tatam
vināśam avyayasyāsya
na kaścit kartum arhati

Translation

That which pervades the entire body you should know to be indestructible. No one is able to destroy that imperishable soul.

antavanta ime dehā
nityasyoktāḥ śarīriṇaḥ
anāśino ‘prameyasya
tasmād yudhyasva bhārata

Translation

The material body of the indestructible, immeasurable and eternal living entity is sure to come to an end; therefore, fight, O descendant of Bharata.

ya enaḿ vetti hantāraḿ
yaś cainaḿ manyate hatam
ubhau tau na vijānīto
nāyaḿ hanti na hanyate

Translation

Neither he who thinks the living entity the slayer nor he who thinks it slain is in knowledge, for the self slays not nor is slain.

na jāyate mriyate vā kadācin
nāyaḿ bhūtvā bhavitā vā na bhūyaḥ
ajo nityaḥ śāśvato ‘yaḿ purāṇo
na hanyate hanyamāne śarīre

Translation

For the soul there is neither birth nor death at any time. He has not come into being, does not come into being, and will not come into being. He is unborn, eternal, ever-existing and primeval. He is not slain when the body is slain.
