According to the Buddha, there are millions of buddhas and many heavens and hells to where one's next birth can direct. The human plane of existence is one of the many possibilities, the other planes are of several levels of demonic and animalistic beings. The different schools of Buddhist thought are not in full agreement over the numbers and the names and styles of all the heavens and hells, but they all agree that there are many. The lower number is 30 heavens and hells.
With regards to miracles, Buddhism does not shy from these. Gautama Siddharta Buddha performed more miracles that Teacher Jesus, and grander ones at that.
Some westerners would like to create a neo-buddhism that is only a philosophy with no deities, heavens, hells and miracles, and especially with no human soul and no future after human death. They want something that is not a religion. Buddhism is a very importantant religion that serves at least two billion worshippers who pray to the Buddha and get intercessory prayers and blessings from monks on a daily basis. It is preposterous to tell stories that Buddhism is not a religion, and has no deities.
To read about Gautama Buddha's teaching how people have life after death in manifested individual forms, where they have names and individual chateristics, read ANY of of the 100,000 plus sutras and you will see talk of spiritual beings, assemblies of gods and vast numbers of heavens and spiritual realms filled with beings of all kinds. Unlike what some westerners tell people, Buddhism has a very busy afterlife in which souls are entities with characteristics and karmic debts that need to be personally accounted for. The western idea that there is no afterlife, that there is no ego, there is no self to exist after this coming death--is not the Buddhism that millions of Buddhists live and celebrate every day.
As I write this page, the sounds of three different Buddhist pagodas reach my ear. There is a wedding going on in the neigbourhood and monks are in attendance for a fee, to deliver prayers, blessings and to clean the home of evil spirits. The funeral at the closest pagoda is very loud and had been going on for several days, it must be some government official or a senior monk. It is a very grand affair. The streets of my city are always a bustle of religious activities be it for child monks being inaugurated, or programs to bring a host of new monks on board because monking is a haven for people running from the law and from poverty. Cambodia has about 50,000 monks, Thailand has 450,000 in 2020, and the population must feed, clothe and educate the monks out of their own pockets. In return, the monks will meditate to try and gain elightenment and by that, society will get good merits. This is the standrad Buddhism of SE Asia. It is a beautiful religion and the people benefit from all the religious activities going on.
Westerners should not comment on Buddhism unless they have lived in a Buddhist society. Studying Buddhism, or any ideology or religion at university or in a monastery is only a small part of its reality. We urge Wayists to be careful of latter-day Western Neo-buddhism because it is not always the truth and several billions of people will disagree with the handful of Neo-Buddhists in the west.
