Regarding the commentary's "However, in terms of inferior cognition being unable to reach it": this explains the esoteric meaning above. Therefore, the Lotus Sūtra says: "I, through countless upāyas, various causes and conditions, similes, and words, expound all phenomena; this Dharma cannot be understood by thought and discrimination; only buddhas can know it. For what reason? The buddhas, the World-Honoured Ones, appear in the world solely for one great cause and condition." Explanation: The various expoundings of the Dharma are all for the One Vehicle; because sentient beings do not know this, it is called secret. From "Therefore the Nirvāṇa [Sūtra]" downward, it cites proof, which is also as cited before.
