觀無量壽佛經義疏 3.233

3.233

"‘When such a foolish person approaches the end of his life, he meets a good friend who comforts him in various ways, expounds the wondrous Dharma for him, and teaches him to be mindful of the Buddha.’" Expounding the wondrous Dharma means praising the Pure Land. Teaching him to be mindful of the Buddha means performing contemplation. Second, the inability due to painful illness.
