The first reason why Emperor Jiaqing was addicted to monasticism was that he wanted to live forever. As the king of a country, the monarch holds supreme power, so many monarchs can't give up this right in their hands, and Emperor Jiaqing is no exception. He hoped that he could master this power for a long time, so he hoped that he could live forever, so that he could sit on the throne of the monarch forever, and the only way to live forever was to indulge in cultivating immortals, so this was the first place where Emperor Jiaqing indulged in monasticism.
The second reason why Emperor Jiaqing was addicted to the road of monasticism was that he hoped to improve his physique through monasticism. Emperor Jiaqing was sickly and physically poor since childhood. Even after becoming a monarch, enjoying luxurious treatment, his physique has not improved. Emperor Jiaqing was very anxious because of his physical problems. At this time, he was bewitched by some people. He thinks monasticism can keep him healthy. Plus, he took some medicine given to him by monks, which was very effective, so he embarked on this road of no return.
To sum up, Emperor Jiaqing was addicted to monasticism and neglected state affairs for several reasons. In ancient history, many monarchs were very addicted to the road of enlightenment because they all wanted to hold power firmly in their hands and didn't want to be so old. At that time, people were superstitious about feudalism and thought that there really was such a thing as cultivating immortals. Therefore, many monarchs are addicted to self-cultivation, which leads to the neglect of state affairs and the dissatisfaction of many ministers.
