In Vishista-advaita Vedanta dharmayudha is an intrinsic component and necessarily so. How does one respond to injustices inflicted upon one, is the question. Does one attack or defend?

It comes about when one is not attached to anything and then truth descends into the mind to show the way forwards such that one will always end up truth-accommodating to the imminent realities
