The word “yoga” comes from the Sanskrit root “south”, which means “to connect.” The Lithuanian root “jung” (to connect, yoke) and the Russian word “yoke” – from the same root. The original meaning of the word yoga was very close to the meaning of the word yoke. The verb root “south” meant: join something, equip for any purpose. Consequently, in the first meaning, the root “south” contained the idea of preparing for hard work, just like the usual European expression “harness something”.
Yoga is a system of moral self-improvement, which is part of many religious and philosophical concepts of India. The first goal of the training required by yoga is to teach a person to properly obey the laws of moral and physical nature, since yoga believes that the achievement of moral and spiritual perfection depends on this submission.
If the goal is to develop supernormal mental forces, working on yourself for the purpose of this development is called yoga. The same word is used to denote the mental training necessary to achieve complete control over thoughts and feelings, to achieve spiritual perfection.
There are four main Yogis – Karma Yoga, Jnana Yoga, Bhakti Yoga and Raja Yoga. These Yogis are described in detail in four books written by the Indian philosopher Swami Vivekananda and published in 1914 – 1915; they were published in Russian in pre-revolutionary times.
Karma Yoga is the path of action. The secret of the right work, or the right activity that Karma Yoga teaches, is to work for work, and not for rewards, to do results, not to care about the fruits, but simply in order to gain experience and unleash your strengths and abilities . The follower of this Yoga does not pay attention to success or failure in his life, he tries to do the best that he can, tries to put as much energy into all his efforts as there is in him.
