The Lotus Sūtra is incomparable to any other sūtras preached by Śākyamuni Buddha during His lifetime. As stated in it, it is the sūtra understood only by Buddhas. This means that all those between the bodhisattva of the highest stage and the unenlightened are unable to understand it. Therefore, it is stated in the Great Wisdom Discourse attributed to Bodhisattva Nāgārjuna of India: “Those below Buddhas can attain Buddhahood only through faith.”
