The earliest yoga is more than two million poses, which was founded by Hindu Shiva and spread all over the world. Every action symbolizes a disaster in life. If you successfully complete all asanas, you can avoid the pain of reincarnation.
The original intention of yoga is contact and coordination, and it pursues the harmonious unity between man and the universe, which is very similar to China's thought of the unity of man and nature. After reaching this state, self-defense is only a very simple thing, just because there is no fighting heart and no desire for self-defense
Buddhism in China originated from India, and martial arts originated from Shaolin, which believes in Buddhism. It was originally just a practice method for monks to keep fit. Hinduism came into being much earlier than Buddhism. Why can't yoga, a physical exercise method adopted by Hindu monks, have the effect of fighting? It's just a question of whether practitioners are willing or not.
Some popular examples may be indirect.
Most Asian countries have their own traditional fighting techniques, such as martial arts, Thai boxing and karate. But I have never heard of the traditional fighting skills in India. Is it true that India, an ancient civilization with a history no less than that of China, has no war since ancient times and needs no training? In fact, most Indian soldiers still practice yoga, which is similar to the purpose of the PLA to practice military boxing.
Let's make an extreme hypothesis. Everyone should have seen the performances of yoga masters such as stepping on glass and piercing nails, showing extreme tolerance for pain. In fact, hatha yoga and some tantric yoga often use knives to help "transform" themselves, and their tolerance to skin trauma is almost equivalent to the effect of iron cloth shirts in martial arts legends. Think about how hard it is to face an enemy who is not afraid of pain as a zombie. What if it is a group of soldiers who are fearless and 100% carry out their orders?
