The original handwritten manuscript, found in the Chisan Archives (Chishaku-in, Kyoto) on the bottom half of Page 239 of Scroll 1 in the “Texts Stored in the Chisan Repository,” is titled “An Exegesis of the Illuminating Secret Commentary on the Five Chakras and the Nine Syllables.” Published as Volume 5 of the “Collected Treatises of the Chisan School of Shingon Buddhism,” it includes five scrolls and five books.
