सुखदुःखे समे कृत्वा लाभालाभौ जयाजयौ। ततो युद्धाय युज्यस्व नैवं पापमवाप्स्यसि॥
sukha-duhkhe same kritva labhalabhau jayajayau tato yuddhaya yujyasva naivam papam avapsyasi
Translation
Treating happiness and sorrow, gain and loss, victory and defeat alike, engage in battle. Thus you will not incur sin.
Commentary
This is the key teaching of equanimity in action. By remaining balanced in all opposites, action becomes purifying rather than binding. This principle transforms duty from burden into spiritual practice.
