Yoga can be found anywhere because this era take the fashion of well-being. Even in Bible colleges, even within the church yoga has brought up. Today, yoga has gained great popularity. Around these days it is not difficult to find people indulged in the charm of yoga. Due to the global well-being, Yoga is causing a sensation in popularity. In the 1970s, in Korea yoga began to be introduced. Domestic population of Yoga has exploded recently in between 2-3 years, Yoga’s population is over a million people. Even it is estimated to be ranging from a few hundred million. With well-being, a report shows Yoga’s population will increase by 5,000 people a day. So there is Yoga school more than 300 in the nation. On famous domestic portal sites ‘Daum’, there are more than 500 yoga-related community. Yoga was thought to be as Indian esoteric ideas, or the body bit strange behavior, Yoga is coming into the modern life combined with fitness business. Thus on the rise in popularity of yoga these days, more and more Christians are questioning about yoga. And Christians are also questioning about ‘what is yoga?’ and ‘whether we can do yoga?’However, many Christians do yoga already, and many Church also actively accepts it. Many Christians are doing yoga for their health. However, because yoga is a Hindu, if you do yoga, it is religious syncretism. Because yoga leading to the liberation is Hinduism, yoga for Christians is to become a religious syncretism. Because yoga is a Hindu itself. Yoga is not one of the mental and physical discipline but practice of Hinduism as a way leading to enlightenment. There are four kinds of the core of the Hindu spirit. It is Karma, Maya,Nirvana, and Yoga. In other words, there are four kinds that leads us to the heart of Hinduism. It is karma, Maya, nirvana, and yoga. Hinduism came from the pursuit of post-Vedic era more than anything else, and it was about the four concepts. First, the Law of Karma- The universal law of cause and effect connection between humans and the universe infinitely recurring human past lives is sentenced, Second, the Maya- orderly Space Systems raises to keep the mysterious process, these developments in the presence of “eternal return” and fundamental ignorance or obscure(avidya)in the infinite as human beings their mistaken to immerse, Third,Nirvana- Maya by karma and by the entangled condition of human experience, built in the real world beyond the realm of reality. Finally, yoga- a means of acquiring real presence, an effective technique to gain enlightenment. In Hinduism, the truth itself is considered insignificant. The truth is considered as the ability to save the world only. In Sages of India to pursue their goal is to obtain absolute freedom not to gain wisdom but true liberation through wisdom. That is yoga. Thus, Yoga is not just a exercise or posture but a training for liberation to get away from the eternal cycle. Therefore, yoga is a Hindu itself. That yoga is not a simple exercise but to perform a Hindu. Therefore, if Christians do yoga it means to become religious syncretism, because doing yoga means to believe Hinduism. Christian-yoga is called the Old Testament ‘Jehovah-Baal’, which will look into the concept of speaking, the New Testament that ‘Jesus-guru’.
