आत्मनश्च परित्राणे दक्षिणानां च सङ्गरे । स्त्रीविप्राभ्युपपत्तौ च घ्नन् धर्मेण न दुष्यति ॥ ३४९ ॥
sanskrit
In their own defence, in a strife for the fees of officiating priests, and in order to protect women and Brahmanas; he who (under such circumstances) kills in the cause of right, commits no sin.
