Day 30 covers all of Chapter 26, Dhāraṇīs

Having last month received Brave-In-Giving Bodhisattva’s dhārāni spells, we receive Vaiśravaṇa Heavenly-King’s dhārāni spells.

Thereupon Vaiśravaṇa Heavenly-King, the Protector of the World, said to the Buddha, “World-Honored One! I also will utter dhārānis in order to protect this teacher of the Dharma out of my compassion towards all living beings.”

Then he uttered spells, “Ari (1), nari (2), tonari (3), anaro (4), nabi (5), kunabi (6).”

[He said to the Buddha:]

“World-Honored One! I will protect this teacher of the Dharma with these divine spells. I also will protect the person who keeps this sūtra so that he may have no trouble within a hundred yojanas’ distance [from here].”

It is appropriate here to offer Nichiren’s understanding of the promise these spells entailed:

Life is fleeting! No matter how many powerful enemies join forces against you, do not retreat and never be afraid. Even if your head is sawed off, your torso pierced through with a spear, and your feet shackled and drilled with a gimlet, you should continue chanting “Namu Myōhō-renge-kyō” as long as you have life. If you die chanting it, Śākyamuni Buddha, the Buddha of Many Treasures, and Buddhas in manifestation throughout the universe will immediately come flying, lead you by the hand or carry you on their shoulders to Mt. Sacred Eagle as they had promised at the assembly on Mt. Sacred Eagle. At that moment, two sages (Bodhisattvas Medicine King and Brave Donor), two heavenly kings (World Holding and Vaiśravaṇa), and ten female rākṣasa demons will protect you, upholders of the Lotus Sūtra, and various gods and deities will hold up a canopy over your head, wave banners, guard you, and certainly will send you to the Jeweled Land of Tranquil Light. Is not this the utmost happiness?
