Since there are no "wise disciples" [priests] in the SGI Order, how can the Law long endure?

"The Nirvana Sutra says: 'Within the Order there are wise disciples who understand profound doctrines, while in secular circles there are pure-minded lay supporters. Thus the Buddha’s Law will long endure.' Thus the Great Teacher T’ien-t’ai talked Mao Hsi and others into supporting him, and the Great Teacher Dengyō had Kunimichi and Hiroyo to rely upon."
