There are rākṣasas called 1. Lambā, 2. Vilambā, 3. Crooked-Teeth, 4. Flower-Teeth, 5. Black-Teeth, 6. Many-Hairs, 7. Insatiable, 8. Necklace-Holding, 9. Kuntī, and 10. Plunderer-Of-Energy-Of-All-Beings. These ten rākṣasas [and their attendants] came to the Buddha, together with Mother-Of-Devils and her children and attendants. They said to the Buddha simultaneously:
“World-Honored One! We also will protect the person who reads, recites and keeps the Sūtra of the Lotus Flower of the Wonderful Dharma so that he may have no trouble. No one shall take advantage of the weak points of this teacher of the Dharma.”
Then they uttered spells before the Buddha:
“Ideibi (1), ideibin (2), ideibi (3), adeibi ( 4), ideibi (5), deibi (6), deibi (7), deibi (8), deibi (9), deibi (10), rokei (11), rokei (12), rokei (13), rokei (14), takei (15), takei (16), takei (17), tokei (18), tokei (19).”
[They said to the Buddha:]
“Anyone may step on our heads, but shall not trouble this teacher of the Dharma. Neither shall any yakṣa, rākṣasa, hungry spirit, pūtana, kṛtya, vetāda, kumbhāṇḍa, umāraka, apasmāraka, yakṣa-kṛtya or human kṛtya. Neither shall anyone who causes others to suffer from a fever for a day, two days, three days, four days, seven days or forever. Neither shall anyone who takes the shape of a man, a woman, a boy or a girl and appears in his dream.”
Then they sang in gāthās before the Buddha:
Anyone who does not keep our spells
But troubles the expounder of the Dharma
Shall have his head split into seven pieces
Just as the branches of the arjaka-tree [ are split].
Anyone who attacks this teacher of the Dharma
Will receive the same retribution
As to be received by the person who kills his parents,
Or who makes [sesame] oil without taking out worms [from the sesame],
Or who deceives others by using wrong measures and scales,
Or by Devadatta who split the Saṃgha.
Having sung these gāthās, the rākṣasas said to the Buddha:
“World-Honored One! We also will protect the person who keeps, reads and recites this sūtra, and acts according to it so that he may be peaceful, that he may have no trouble, and that poison taken by him may be neutralized.”
It is believed that the root of the word dharani in Sanskrit is the verb dhuti, which means “to keep or maintain.” Probably the original meaning of dharani was to keep or maintain something in the memory. It was necessary for people learning a sutra to be able to remember its words and recite them accurately.
