What I say here may not be correct, it is for reference only! First of all, from the late Qing Dynasty (before the Empress Dowager Cixi) to the Han Dynasty, Buddhism was never a religion in China, but belonged to the educational field, and was classified as a religion, which was changed by the Empress Dowager Cixi; secondly, , Emperor Yongzheng (actually Emperor Shunzhi is also) is a great protector of Buddhism, but there is no connection between refining elixirs and attaining the throne of the emperor. The throne of the emperor is obtained by cultivation in his previous life; thirdly, Tushita Heaven is the heaven from the bottom to the top. The fourth heaven, from bottom to top: the heaven of the four kings, the heaven of Traitors, the heaven of Ye Mo, the heaven of Tusita, the heaven of Hua Le, the heaven of other transformations...the sky of emptiness, the sky of consciousness, the sky of nothingness, There are 28 levels of heaven in one world, and Maitreya Bodhisattva is currently teaching the Dharma in the backyard of Tusita. No matter how heavy the killing karma is, it is impossible for a Bodhisattva to demote him. Otherwise, where would the Bodhisattva's compassion be? Right? Not only will the Bodhisattva not demote him, but if he is suffering in the lower realms, the Bodhisattva will try his best to save him! Fourth, China’s Qing Dynasty has been talking about the unification of the three religions (Buddhism, Confucianism and Taoism) since the former Qing Dynasty, and implemented the strategy of unification (although there have been objections for more than 200 years in the Qing Dynasty). No matter the famous mountains and rivers, there are three religions everywhere. There are traces of the teaching of harmony, which we can see in many famous mountain tourist attractions; fifthly, the "alchemy" that Taoism talks about is not really refining pills. This is a misinformation that has been misunderstood for thousands of years. People take the true meaning inside The meaning was misunderstood, and it was passed down through false rumors. This phenomenon has existed both at home and abroad in ancient and modern times. There are three schools of Buddhism, Confucianism and Taoism. Buddhism talks about compassion, Confucianism talks about benevolence and righteousness, and Taoism talks about truth. Although they use different words, if you observe and understand them carefully, they actually mean the same thing, which is to live, work, and treat others in accordance with nature. Get along with everything! We must know this! Therefore, the rumors about alchemy extending life or political reasons are not true (I don’t know which historical book you saw the theory of "alchemy extending life" you mentioned? I have never heard of it, I have only seen the saying that it was political reasons). Finally, I will briefly introduce the correct meanings of several terms: 1. Buddhism---Buddha's education! It is education and teaching, not what we call "religion" now! 2. Religion---Zongmen Jiaoxia. In China, "Zongmen" specifically refers to Zen. Sects other than Zen are called "Jiaoxia", or "religion" for short. This is how the word comes from! 3. Buddha, Bodhisattva, Arhat - this is a degree term. Just like in our universities now, undergraduates are called "Arhats", master's students are called "Pratyekabuddhas", doctoral students are called "Bodhisattvas", and finally When you reach perfection, you are called "Buddha"! 4. Monk---"Monk" is Sanskrit, which translates as "teacher", which is the teacher who teaches us personally. This is what it means. 5. Abbot. First seat. Supervisor---"Abbot" is the president of the university, in charge of various temple affairs; "First seat" is the provost of the university, in charge of teaching; "Supervisor" is the director of administrative affairs in the university , supervise and manage various affairs rituals, visitor reception, rules and regulations, etc.
