UtshovBhagavad Gita 2.38
सुखदुःखे समे कृत्वा लाभालाभौ जयाजयौ।
ततो युद्धाय युज्यस्व नैवं पापमवाप्स्यसि।।2.38।।
Sukhaduhkhe same kritva labhalabhau jayajayau
Tato yuddhaya yujyasva naivam papamavapsyasi
Simple meaning, written by AITreating pleasure and pain, gain and loss, and victory and defeat as equal, then engage in battle; in this way you will not incur sin.
