Yoga is called a spiritual process in India and Nepal in which the work of bringing body, mind, and soul together (Yoga) is done. This word, process and perception is related to meditation process in Buddhism, Jainism and Hinduism. Yoga has also spread with Buddhism from India, China, Japan, Tibet, Southeast Asia and Sri Lanka and at this time people are familiar with it in all the civilized world.
After so much fame, for the first time on December 11, 2014, the United Nations General Assembly has recognized each year on June 21 as World Yoga Day. Bhagavad Gita is considered as a sacred scripture. The word yoga has been used many times, sometimes alone and sometimes, such as Buddhiyog, Sanyasayog, Karmayog. In the post-Vedic period, bhaktiyog and hatha yoga have also become prevalent, in Patanjali Yogasarshan it comes to see Kriya Yoga. Words like Pashupat Yoga and Maheshwar Yoga are also found. In all these places, the meaning of the Yoga word is against each other, but seeing different types of these experiments makes it clear that definition of yoga is a difficult task. The definition should be such that it is free from the non-separation and overlapping defects, to indicate the meaning of yoga, which is suitable for every context and not suitable for anything other than yoga.
In the Gita, Shri Krishna has said at a venue: ‘Yoga: Karmasu Kaushalam’ (Yoga comes skillfully in karma). It is clear that this sentence is not a definition of yoga. It is the opinion of some scholars that Soul and Divine are called yoga. It is a big obstacle to accept this fact that even Buddhists, who do not accept the power of God, behave in Yoga and support yoga.
The same can be said for the numerologists who consider the power of God as inferior. In Yogadarshan, which is given a definition, ‘Yogatyattapatikanvadar’, Yoga is the name of the detention of the teachings of the mind. This sentence can have two meanings: the name of the condition of the detention of the consciousness is yoga or the remedy to bring this state is called yoga.
