What is the ruling of practising yoga? The short answer is…
Yoga is a method applied to help people be purified and achieve the truth by having them acquire certain religious knowledge and talents in Hinduism and Buddhism.
In recent years, most of the yoga centers, which have become widespread in our country as activities of physical exercise and psychological therapy, operate by dissociating themselves from these religions and say that they are independent yoga practitioners. However, the discourses of yoga’s not having a religious aspect and only being exercises for mental purification do not fully reflect the truth. Because yoga exists as a religious practice in Indian religious (“Brahmanism”, DİA, VI, 331).
Accordingly, it is not appropriate for a Muslim to practice yoga by knowing that it depends on the belief and worships of another religion.
