Tao-sheng Commentary on the Lotus Sutra, p333There 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 {Robber of the Vital Vapors of All Living Beings}.
Daughters of rākṣasas and others, ten female demons, possess great powers in the world. They are the mothers of various demons. They respect and obey the Buddha’s orders, as they also pronounce this charm. Even though the demons are wicked, they do not disobey their mothers. As their mothers obey the Buddha, so their sons follow them.
In the heart of a man there are seven [measures of] mucus sweet water for nourishing human life. If a rākṣasa enters into a man’s body, and drinks one mucus, then he (the man) suffers a head illness. If [the demon] drinks two, three, or four [measures of] mucus, then the man loses consciousness. This is curable, but if he is left there he is bound to die. Thus, he is “robbed of vital vapors.”
