Bhagavad Gita 2.19

य एनं वेत्ति हन्तारं यश्चैनं मन्यते हतम्।उभौ तौ न विजानीतो नायं हन्ति न हन्यते ॥२.१९॥

ya enaṃ vetti hantāraṃ yaścainaṃ manyate hatamubhau tau na vijānīto nāyaṃ hanti na hanyate

He who takes the Self to be the slayer and he who thinks it is slain, neither of them knows. It does not slay, nor is it slain.
