Wukong, Wuneng and Wujing are all of profound significance. They respectively responded to the different requirements for the three of them, which also reflected their personality and practice before learning the scriptures. Only by meeting these requirements can we achieve perfection and finally achieve positive results.
First of all, the Monkey King's practice is the most profound among the three, but Wukong himself is persistent, and his heart can't stop. There is an idiom "in a spirit". It is a metaphor for people's wandering minds, which are as difficult to control as monkeys and horses. The Monkey King himself is a monkey, and his heart can't stop being natural and normal. Named Wukong, I want Wukong to settle down, let go of his obsession, realize the emptiness and purity, sincerely follow Buddhism, and finally achieve a positive result.
The second brother, Bajie, is also called Wuneng, and "neng" should mean ability. Pig's mana practice is still relatively advanced, so it is no problem for Bajie to practice. However, Zhu Bajie's desire is too much, he is lazy all day, and he is also greedy for beauty, which are obstacles in his practice. Going to this name is also to enable Pig Bajie to control his own desires, so as to achieve positive results.
Third Junior Brother Wu Jing is a low-key person, and his cultivation is not profound, but just so-so. Wu Jing means to be refined and understand Buddhism, and to be refined and purify all beings. Therefore, Wu Jing was named because he could get a clean heart and not compete with the world, so he was relatively inconspicuous in Journey to the West, just doing some coolies.
What's more, the names of the second and third brothers were not taken by Tang Priest, but by Guanyin Bodhisattva. Wukong was not taken by Tang Priest, but by the Monkey King's father, Bodhi, so we should not all think that Tang Priest took all their titles.
