How did Nichiren understand [Nirvāṇa Sūtra stories of people killed for slandering the Mahāyāna]? In Risshō Ankoku-ron, Nichiren stated that while King Sen’yo and King Virtuous may have killed slanderers of the Dharma in the past, since the appearance of Śākyamuni Buddha the correct method is to simply deny them offerings. The Nirvāṇa Sūtra told those stories of the previous lives of Śākyamuni Buddha in order to emphasize the gravity of slandering the True Dharma and the great virtue of defending the True Dharma but such methods are not being advocated in the present. Instead, the withholding of alms and especially state support from corrupt monks and the support and protection of true monks should now be followed. In accordance with our current laws and the wise separation of church and state, I believe this means that each of us must discern what teachings or causes we should or should not support with our time and money and that the protection of the law should extend equally to all so that there will be no question of religious persecution arising from either the government or the actions of private individuals or institutions. Every religious or spiritual teaching should be free to stand or fall on its own merits or lack thereof.
