In Journey to the West , why did only the mounts of the three major Bodhisattvas go down to the ear

Personally, I feel that it is very likely that the mount of another bodhisattva is not free to go down to the mortal world.

Because Guanyin Bodhisattva's mount was very obedient, only a few other Bodhisattva's mounts went down to the earth to make trouble.

The mounts of the three bodhisattvas all descended to the west of Tang Sanzang and completed the task of the trilemma. On the surface, these tasks are to improve the level of cultivation for the cultivation of Tang Sanzang and his party, and to help these Tang monks and apprentices who are obsessed with learning scriptures from the West.

Manjushri's mount is a green lion, Guanyin's mount is a golden retriever, Puxian's mount is a six-tusked white elephant, and Jizo's mount is Diting. Jizo Bodhisattva's mount ** in Jiuhua Mountain is the treasure of Jiuhua Mountain, Guanyin Bodhisattva's mount is the son of the Dragon King, Fuxian Bodhisattva's mount is an animal drawn by Guanyin, Manjushri Bodhisattva's mount dojo in Shanxi Wutai Mountain.

Manjushri's mount is a green lion, and its origin and sayings imply wisdom and the absence of afflictions. The Bodhisattva mount is a six-tusked white elephant, which means wisdom and meditation. Guanyin Bodhisattva's mount is a golden retriever, which means to spread the will of heaven and send down the people's feelings.

Jizo Bodhisattva's mount is a unicorn. The saying is to listen well and speak well.

The Four Great Bodhisattvas: Manjushri, Puxian, Guanyin, Jizo; Manjushri symbolizes wisdom, called great wisdom, mounts as green lions, and takes Wutai Mountain in Shanxi as the dojo; Fuxian Bodhisattva symbolizes the wish, called the great line, the mount is a six-tusked white elephant, and Mount Emei, Sichuan is its dojo; Guanyin Bodhisattva symbolizes compassion, called great compassion, the mount is the roar of the golden retriever, and Putuo Mountain in Zhejiang is its dojo; Jizo Bodhisattva symbolizes the power of the wish, called the great wish, the mount is the truth, and the Jiuhua Mountain in Jiangxi Province is its dojo;

Manjushri. Puxian Bodhisattva.

Guanyin Bodhisattva. Jizo Bodhisattva.

Just because hell is not empty and he cannot become a Buddha, he can distinguish between good and evil, and knows that he is an obstacle on the way to learning scriptures, and it is superfluous for him to go, and he also delays making merits.

Because Di Ting wants to follow its master to transform the dead in hell, the Jizo King Bodhisattva also needs it to distinguish between right and wrong, good and evil.

Because the ability to listen is too great, Jizo Bodhisattva did not let it join the camp of the Monkey King.

Manjushri is a lion, Fuxian is a six-tusked white elephant, Guanyin is a dragon, and Jizo is a divine beast.
