Translated by T. Danilevich Yoga is the name of the Teaching of the means of achieving spiritual Perfection. Implied is removal of one's personal separation, harmonious merging of individual with macro-ecosystem.
Yoga is a religious teaching.
The basic literary source of yoga is Indian Bhagavad-Gita, composed a few thousand years ago. As it was mentioned above, the goal of the yoga teaching is religious. It consists of achieving by the individual human consciousness that went through preliminary prolonged evolution, with the Creator's Consciousness. But if you are still unable of doing it now, says He, practice preliminary meditations. And if the technique of meditations is difficult for you as yet, learn to perform everything that you do in your life not for your personal benefit, but devote these actions to God.
