In Sanskrit:
वेदाविनाशिनं नित्यं य एनमजमव्ययम् ।
कथं स पुरुषः पार्थ कं घातयति हन्ति कम् ॥
vedāvināśinaṃ nityaṃ ya enamajamavyayam
kathaṃ sa puruṣaḥ pārtha kaṃ ghātayati hanti kam
Translation (Meaning in English):
O Partha, how can a person who knows that the soul is indestructible, unborn, eternal and immutable, kill anyone or cause anyone to kill?
Lessons:
The lesson from this Bhagavad Gita verse is that the true self, the soul, is eternal and indestructible. It cannot be killed, nor can it kill. It is the body that is mortal and subject to birth and death.
Therefore, we should not be attached to the physical body and should not cause harm to others or ourselves. This shloka teaches us to recognize the true nature of ourselves and others, and to act with compassion and wisdom.
