[Chapter 25, The Universal Gate of World-Voice-Perceiver Bodhisattva,] says that if someone calls the name of this Bodhisattva, he or she will be able to avoid seven calamities. Such benefits, by which one can avoid calamities and obtain happiness, are called “benefits in this world.” The teachings of this chapter list many of them. However, to obtain such benefits, we must have pure hearts. The Buddha and the Bodhisattvas grant such benefits only to people who practice sincerely. The purpose of calling the name of World-Voice-Perceiver is really to show our sincerity to him. This is made clearer in the next lines, which mention basic virtues such as sincerity, patience, and wisdom.
Lustful persons will be relieved of lust if they think about Bodhisattva World-Voice-Perceiver. Angry people will calm down if they think about him and respect him. Perplexed people will acquire clarity of mind if they think of him and respect him (p. 317).
Lust, resentment, and stupidity are called the “three poisons” in Buddhism. They are sometimes translated as greed, anger, and ignorance. The seven calamities are material and physical sufferings of human nature, and the three poisons are mental sufferings. Material sufferings come upon us because the mental sufferings exist already as their bases. If our suffering minds are healed of the three poisons, we can expect material calamities to disappear, too.
