No, it is not. Yoga can only be called a system of self-knowledge that strictly adheres to the first principle of yoga, or the principle of kindness, and the second principle, or the principle of common sense.
The first principle tells us that we "must not harm any living being unless absolutely necessary; if it is not possible not to harm, then we must do as our duty dictates." This principle is the cornerstone of any system of self-knowledge, without observing it, it is impossible to rise to a new spiritual level.
The second principle, or the principle of logic, tells us that " we should not waste our time and energy on small things. We must first be very clear about our goals, whether they are in work, study, yoga, or any other field of activity, and then direct all our efforts only to achieve these goals.
Therefore, before engaging in another activity, we must ask ourselves whether it leads us to the goal, and if not, we must ruthlessly reject it, no matter how tempting it may seem to us."
By following the first and second principles, sooner or later we intuitively "feel" our life path, which is called dharma, or destiny, and by following it, we achieve all our goals faster and at the same time become more aware of our duty.
In principle, there are no external devices or diagnostic methods to determine whether a particular yoga exercise is being performed correctly. No outside observer can do this, only the practitioner can determine it.
At the same time, yoga provides some guidelines for how to do this – when performing each exercise in yoga, you should feel harmony and a state of joy. If you are doing an exercise and you want to keep doing it, then you are doing it correctly. You can feel the joy of overcoming yourself by performing a pose with effort, using will, or, conversely, the joy of experiencing pleasant sensations in the body when the pose becomes comfortable, but in both cases there should be positive emotions.
If you feel pain, discomfort, a desire to get out of the pose, but use violence on your body, then you do anything but yoga. In yoga, it is believed that violence against the body is absolutely not effective and does not lead to any long-term results. As it is said in an ancient treatise on yoga, "pain and yoga are incompatible, if there is pain-there is no yoga, if there is yoga-there is no pain."
This is the main secret of yoga, this is what distinguishes it from physical education and sports. It is thanks to the harmony method that you begin to feel better about yourself, move from the outside world to the inside, and begin to grow spiritually. It is this method that allows you to get all the useful effects of yoga - to develop and hone your intellectual abilities, learn how to plan and achieve your goals, build harmonious relationships with others, and much, much more.
If we briefly structure the whole variety of effects obtained from yoga, we can answer this question as follows:
Physical health, good energy tone, a surge of energy and vitality.
A beautiful, hardy, slender physical body.
Mental health, stress relief, calmness, balance, inner harmony and freedom, a sense of joy and happiness.
Real positive changes in life - more interesting and well-paid work, a rich, interesting life, building more harmonious relationships with others, freeing up time resources, achieving all the goals set,
Spiritual development – a person becomes more open, kind, sincere, begins to understand himself and the Universe better, becomes a support for other people.
