First, Indians mainly believe in Hinduism, and few people believe in Buddhism. Everyone has seen The Journey to the West, and the Tianzhu mentioned in it is today's India. Buddhism once flourished in India after Sakyamuni founded it. Brahmanism, the predecessor of Hinduism, was very popular before Buddhism was founded. With the growing prosperity of Buddhism, the status of Brahmanism is threatened. Later, Brahmanism reformed, absorbed the elements of Buddhism and became Hinduism. With the rise of Hinduism, it gradually replaced Buddhism.
There are very few people in India who believe in Buddhism now. At present, more than 80% people in India believe in Hinduism, about 10% people believe in Islam and 1%-2% people believe in Sikhism. In India, the number of people who believe in Buddhism is less than 1%, even lower than that of Christians. More importantly, modern Indian Buddhism was introduced from Sri Lanka after19th century, not the original Indian Buddhism. The decline of Buddhism in India can be seen in general.
Second, Indians do not regard Buddhism as their sworn enemy. Indians not only did not regard Buddhism as a deadly enemy, but also shaped the image of the birthplace of Indian Buddhism. Of course, in ancient India, Hinduism once excluded Buddhism. India has always shaped the image of the birthplace of Buddhism, which has aroused strong dissatisfaction in Nepal. The reason why India is like this is actually to create tourism income.
You know, although Buddhism has been very declining in India, it is still one of the three major religions in the world, with 300 million followers. In India, there are many beautiful Buddhist temples. Thanks to this, India can earn hundreds of millions of foreign exchange every year. So, how can India regard Buddhism as its sworn enemy?
Third, the main distribution scope of Buddhism. Buddhism has declined in origin, but it has spread to many countries in East Asia and Southeast Asia. In South Asia, Sri Lanka and Bhutan, they mainly believe in Buddhism; There are a large number of Buddhists in East Asia, China and Japan. In Southeast Asia, Thailand, Myanmar, Vietnam, Cambodia, Laos and other countries are dominated by Buddhism. So Buddhism has indeed declined in India and is still popular in other parts of the world.
Many people must want to know why Buddhism is one of the three major religions in the world, but Hinduism is not. There are more than 654.38 billion Hindus and only 300 million Buddhists. The point is that Buddhism is more widely distributed than Hinduism!
