There are many people who put faith in the teaching of the Lotus Sūtra. Yet as I often experience great difficulties, both public and private, some change their faith after a year or two, even becoming my enemies who shoot arrows at me. Some only outwardly appear to be believers of the Lotus Sūtra, while others believe in the Lotus Sūtra in heart but not in practice.

Śākyamuni Buddha, was the legitimate son of King Suddhodana, a great king who governed the entire continent of Jambudvipa, and all of its 84,210 countries. The kings in Jambudvipa all submitted to King Suddhodana, and he had an innumerable number of domestic servants. Nevertheless, at the age of 19, Śākyamuni left the palace of King Suddhodana, and entered Mt. Dapdaloka, where he spent 12 years practicing asceticism. He was then accompanied by only five men: Ājñāta-Kauṇḍinya, Aśvajit, Bhadrika, Dasābala-Kāśyapa and Mahānāman, two of whom left him in the sixth year and the remaining three also deserted him during the last six years. In the end he continued his training alone until he attained Buddhahood. The Lotus Sūtra is harder than this to have faith in. Therefore the sūtra itself preaches that it is “difficult to put faith in and difficult to understand.” It is also preached in the sutra (“The Teacher of the Dharma” chapter) that the great difficulties that abound today in the Latter Age of Degeneration surpass those that occurred during the lifetime of the Buddha. Therefore the practicer of this sūtra who perseveres through the adversities today acquires more merit than giving alms to the Buddha over the course of a kalpa (aeons).

A little perspective helps appreciate the task of being a practicer of this sūtra.
