The words of Krishna

श्री भगवानुवाच कुतस्त्वा कश्मलमिदं विषमे समुपस्थितम्। अनार्यजुष्टमस्वर्ग्यमकीर्तिकरमर्जुन।।2.2।।

śhrī bhagavān uvācha kutastvā kaśhmalamidaṁ viṣhame samupasthitam anārya-juṣhṭamaswargyam akīrti-karam arjuna

The Lord said: My beloved friend! Why yield to this weakness, on the eve of battle, which does no credit to those who call themselves Aryans and only brings them infamy, barring them from the gates of heaven?

क्लैब्यं मा स्म गमः पार्थ नैतत्त्वय्युपपद्यते। क्षुद्रं हृदयदौर्बल्यं त्यक्त्वोत्तिष्ठ परन्तप।।2.3।।

klaibyaṁ mā sma gamaḥ pārtha naitat tvayyupapadyate kṣhudraṁ hṛidaya-daurbalyaṁ tyaktvottiṣhṭha parantapa

O Arjuna! Why give way to unmanliness? O thou, who art the terror of thy enemies! Shake off such shameful effeminacy and make ready to act!

श्री भगवानुवाच अशोच्यानन्वशोचस्त्वं प्रज्ञावादांश्च भाषसे। गतासूनगतासूंश्च नानुशोचन्ति पण्डिताः।।2.11।।

śhrī bhagavān uvācha aśhochyān-anvaśhochas-tvaṁ prajñā-vādānśh cha bhāṣhase gatāsūn-agatāsūnśh-cha nānuśhochanti paṇḍitāḥ

Lord Shri Krishna said: Why grieve for those for whom no grief is due, yet professing wisdom? The wise grieve neither for the dead nor the living.

न त्वेवाहं जातु नासं न त्वं नेमे जनाधिपाः। न चैव न भविष्यामः सर्वे वयमतः परम्।।2.12।।

na tvevāhaṁ jātu nāsaṁ na tvaṁ neme janādhipāḥ na chaiva na bhaviṣhyāmaḥ sarve vayamataḥ param

There was never a time when I was not, nor you, nor these princes were not; there will never be a time when we shall cease to exist.

देहिनोऽस्मिन्यथा देहे कौमारं यौवनं जरा। तथा देहान्तरप्राप्तिर्धीरस्तत्र न मुह्यति।।2.13।।

dehino ’smin yathā dehe kaumāraṁ yauvanaṁ jarā tathā dehāntara-prāptir dhīras tatra na muhyati

As the soul experiences infancy, youth, and old age in this body, so finally it passes into another; the wise have no delusion about this.

मात्रास्पर्शास्तु कौन्तेय शीतोष्णसुखदुःखदाः। आगमापायिनोऽनित्यास्तांस्तितिक्षस्व भारत।।2.14।।

mātrā-sparśhās tu kaunteya śhītoṣhṇa-sukha-duḥkha-dāḥ āgamāpāyino ’nityās tans-titikṣhasva bhārata

Those external relations that bring cold and heat, pain and happiness come and go; they are not permanent. Endure them bravely, O Prince!

यं हि न व्यथयन्त्येते पुरुषं पुरुषर्षभ। समदुःखसुखं धीरं सोऽमृतत्वाय कल्पते।।2.15।।

yaṁ hi na vyathayantyete puruṣhaṁ puruṣharṣhabha sama-duḥkha-sukhaṁ dhīraṁ so ’mṛitatvāya kalpate

The hero whose soul is unmoved by circumstances, who accepts pleasure and pain with equanimity, is only fit for immortality.

नासतो विद्यते भावो नाभावो विद्यते सतः। उभयोरपि दृष्टोऽन्तस्त्वनयोस्तत्त्वदर्शिभिः।।2.16।।

nāsato vidyate bhāvo nābhāvo vidyate sataḥ ubhayorapi dṛiṣhṭo ’nta stvanayos tattva-darśhibhiḥ

That which is not shall never be; that which is shall never cease to be. These truths are self-evident to the wise.

अविनाशि तु तद्विद्धि येन सर्वमिदं ततम्। विनाशमव्ययस्यास्य न कश्चित् कर्तुमर्हति।।2.17।।

avināśhi tu tadviddhi yena sarvam idaṁ tatam vināśham avyayasyāsya na kaśhchit kartum arhati

The Spirit, which pervades all that is seen, is imperishable. Nothing can destroy it.

अन्तवन्त इमे देहा नित्यस्योक्ताः शरीरिणः। अनाशिनोऽप्रमेयस्य तस्माद्युध्यस्व भारत।।2.18।।

antavanta ime dehā nityasyoktāḥ śharīriṇaḥ anāśhino ’prameyasya tasmād yudhyasva bhārata

The material bodies that this Eternal, Indestructible, and Immeasurable Spirit inhabits are all finite; therefore, fight, O valiant man!

य एनं वेत्ति हन्तारं यश्चैनं मन्यते हतम्। उभौ तौ न विजानीतो नायं हन्ति न हन्यते।।2.19।।

ya enaṁ vetti hantāraṁ yaśh chainaṁ manyate hatam ubhau tau na vijānīto nāyaṁ hanti na hanyate

He who thinks that the Spirit kills, and he who thinks of it as killed, are both ignorant. The Spirit neither kills nor is it killed.

न जायते म्रियते वा कदाचि न्नायं भूत्वा भविता वा न भूयः। अजो नित्यः शाश्वतोऽयं पुराणो न हन्यते हन्यमाने शरीरे।।2.20।।

na jāyate mriyate vā kadāchin nāyaṁ bhūtvā bhavitā vā na bhūyaḥ ajo nityaḥ śhāśhvato ’yaṁ purāṇo na hanyate hanyamāne śharīre

It was not born; it will never die, nor, once having been, can it cease to exist. Unborn, eternal, ever-enduring, yet most ancient, the spirit does not die when the body is dead.
