The image of Friar Sand has always been honest, unlike Pig Bajie, who is so glib and cautious everywhere. Of course, this has something to do with their original position in heaven. Pig Bajie was once a marshal in the sky and one of the four saints in the Arctic. His position is quite high, so he speaks more casually and naturally won't be too restrained. Friar Sand is the confinement general around the Jade Emperor. He is close to the Jade Emperor. He has connections with big shots. He must be careful what he says, and he can't talk casually. The different status makes the lifestyles of Pig Bajie and Friar Sand very different.
In fact, for Friar Sand, the reason why he has been silently dedicating himself is what Guanyin Bodhisattva said to him at the beginning. Guanyin Bodhisattva promised Friar Sand that as long as he helped the eminent monks in the Tang Dynasty learn Buddhism successfully, they could be reinstated. Guanyin Bodhisattva also revealed that learning Buddhism was the above arrangement and an experience.
Hearing this, Friar Sand certainly knew that this was an excellent opportunity. With a master like the Monkey King around, he doesn't have to do anything. He just needs to carry his luggage every day. For Friar Sand, the Monkey King is the guarantee for his reinstatement, and he has awe in his heart.
The novel The Journey to the West seems to describe monsters, but in fact it reflects all kinds of human beings. Friar Sand is the kind of person who is taciturn, inarticulate and cautious everywhere, while Pig Bajie is lazy, but likes to take credit. But they are all kind-hearted in nature, so they all converted to Buddhism in the end.
