Today is the fifth day of the Higan week, the three days before the equinox and the three days after. As explained in a Nichiren Shu brochure:
For Buddhists, this period is not just one characterized by days with almost equal portions of light and dark. Rather, it is a period in which we strive to consciously reflect upon ourselves and our deeds.
The today we consider the Perfection of Vigor. This essay was generated by Google’s Gemini Notebook and then edited for publication here. The essay is derived from the 400 or so letters written by Nichiren uploaded as source material for the Nichiren Notebook.
In the teachings of Nichiren Shōnin, vigor and perseverance are not merely moral recommendations; they are the absolute lifeblood of Buddhist practice and the essential keys to attaining Buddhahood. In the Latter Day of the Dharma, when obstacles are frequent and slanders of the True Dharma are rampant, a follower’s spiritual progress depends entirely on cultivating a courageous, active, and unregressing spirit. Nichiren redefined traditional concepts of Buddhist diligence (shōjin) and laid out several profound principles regarding how practitioners must maintain steadfast endurance.
Redefining True Vigor: Upholding the Dharma
In gradual, traditional Buddhism, diligence was often associated with performing the five paramitas over countless eons. However, Nichiren teaches that in this era, upholding the Lotus Sutra and chanting Namu-Myōhō-renge-kyō constitutes the supreme and only necessary “observance of the precepts” and the true definition of vigor. He cites the Nirvana Sutra to explain that being diligent and non-lax in putting faith in this Great Vehicle means a practitioner is a true observer of the precepts. This diligent practice is compared to polishing a tarnished mirror; through the daily, persistent chanting of the Odaimoku, a mind clouded by innate darkness is actively restored to its original, brilliant clarity.‘To Accept is Easy; To Continue is Difficult’
A core tenet of perseverance in Nichiren Buddhism is the understanding that starting a practice is simple, but maintaining it is where true awakening resides. Nichiren observed that many people become enthusiastic upon first hearing the teachings, but their resolve quickly cools. He contrasted two types of devotion:
- Faith like Fire: Enthusiastic but brief, flaring up quickly and easily extinguished.
- Faith like Water: Ceaselessly flowing, moving steadily forward without ever regressing.
You are encouraged to cultivate faith like flowing water. To illustrate the danger of stopping short, Nichiren used the metaphor of a twelve-day journey from Kamakura to Kyoto. If a traveler journeys for eleven days but stops with only one day remaining, how can they hope to admire the moon over the capital? True perseverance means maintaining your devotion until the very last moment of life.
Hardships as Fuel for Your Enlightenment
Rather than fearing or lamenting difficulties, followers of the Lotus Sutra are instructed to meet obstacles with profound joy and heightened resolve. Nichiren taught that tribulations are the very proof that one is practicing correctly. He used vivid metaphors to show how opposition actually strengthens a practitioner:
- The Fire and Logs: A fire burns more briskly and higher when logs are added; similarly, the votary’s faith grows stronger when fueled by the “logs” of hardship.
- The Kālakula Insect: Just as a strong wind causes the mythical kālakula insect to grow larger, persecutions only expand the life-state of the practitioner.
- The Pine Tree: A pine tree lives for ten thousand years, and its branches naturally become bent and twisted by the winds. In the same way, the long-term practice of the Lotus Sutra will inevitably face great winds of opposition.
- The Forging of Iron: When iron is forged, its hidden flaws are brought to the surface. Put into flames, a common rock is reduced to ashes, but gold becomes pure gold. The trials encountered in life are the fire that purges past offenses and proves faith genuine.
The Courage of the Lion King
Perseverance is impossible without absolute, unyielding courage. Nichiren writes that “it is lack of courage that prevents one from attaining Buddhahood.” He warned his followers that “a coward cannot have any of his prayers answered.”To withstand the pressures of a hostile environment or the doubts sown by others, you must “summon up the courage of a lion king and never succumb to threats from anyone.” While those who slander the Dharma are like barking foxes, the true disciples of Nichiren are like roaring lions. When you confront the storms of life with this fearless attitude, the protective heavenly deities are bound to fulfill their vows and shield you from harm.
The Two Ways of Practice and Learning
Finally, maintaining this vigorous path requires active, daily engagement. Nichiren urged his disciples: “Strive to carry out the two ways of practice and learning. Without practice and learning Buddhism will cease to exist.” True perseverance is not a blind, passive endurance; it is an active study of the Buddha’s intent, combined with the vocal propagation of the Odaimoku. By dedicating your life to these two paths, even amidst the greatest storms of this defiled world, you are promised the eternal, supreme joy of the Land of Tranquil Light.
