Sūta said: This rite should be performed by mighty kings against violent assailants and desperadoes. It should not be practised against brahmins or against the overlord of one’s own realm. This excellent rite shall be performed when a very formidable and invincible enemy has arrived, or when one’s entire army has been slain or when the battle has been waged on sinful lines. The rite shall be performed by one who is devoid of mercy through a merciless person. There is no doubt, that the moment it is performed the power of Nigraha is attained.
