4.105

三問：一切眾生既迷本性已，何故忽然能開悟耶？若言因善知識教法緣熏得開悟者，只如最初一佛，又從何人得法信解開悟耶？

Third question: Once all sentient beings are already deluded about their fundamental nature, why can they suddenly awaken? If you say it is due to the causal perfuming of the teachings of good spiritual friends that they attain awakening, then taking the very first buddha, from whom did he receive the Dharma to generate faith, understanding, and awakening?
