The Miao-fa lien-hua-ching is a Chinese designation for the Lotus Sūtra, which is called the Saddharma-pundarīka-sūtra in India. Tripiṭaka Master Subhākarasimha’s mantras representing the gist of the Lotus Sūtra are as follows: “I put my faith in the everywhere-penetrating Buddha, the three-bodied Buddha. When one attains Buddha Wisdom, which is opened and revealed to all the people, he will, like the crisp-clear sky, be able to get rid of all delusions and evil passions, accept the teaching of the Sūtra of the Wonderful Dharma and live with joy, firmly upholding the teaching.”
These mantras representing the gist of the Lotus Sūtra came from an iron Stupa in Southern India. The Satsuri-daruma among them means the True Dharma, while “satsu” means shō (true) or myō (wonderful). Therefore, the Lotus Sūtra is called either the Sūtra of the Lotus Flowers of the True Dharma or the Sūtra of the Lotus Flowers of the Wonderful Dharma. Placing the two words of na and mu in front of the latter, we get Namu Myōhō Renge-kyō (I put my faith in the Sūtra of the Lotus Flowers of the Wonderful Dharma).
