Chapter 2 · The Yoga of Knowledge · Krishna said
Bhagavad Gita 2.19 — The soul is not killed
य एनं वेत्ति हन्तारं यश्चैनं मन्यते हतम्। उभौ तौ न विजानीतो नायं हन्ति न हन्यते ॥
ya enaṃ vetti hantāraṃ yaścainaṃ manyate hatam ubhau tau na vijānīto nāyaṃ hanti na hanyate ||
Meaning
One who thinks the soul kills, and one who thinks it is killed — both do not understand. The soul neither kills nor is killed.
