It is important to understand that while Yoga is very open to interpretations, it is a practice that has a definition, even a goal and has survived for a few thousands of years, so it means that it worked for some people in achieving that goal they had in mind.
When we go to the scriptures of Hatha Yoga (the physical practices on the path to unity=Yoga)
a very important information can be found in the Hatha Yoga Pradipika (Light on Hatha Yoga) in the very first verse pointing out that Hatha Yoga Leads to Raja Yoga. It is a stair case to Raja Yoga (or the royal Yoga, the Yoga of the mind). So, the goal of our practice, Hatha yoga is to master our mind, understand it and be able to still it.
And to be advanced in Hatha Yoga means that you have developed these abilities, your mind is clear, tranquil, relaxed and comfortable steady and still. These words sound familiar because this is also the definition of an asana (posture). By moving into different postures maintaining this state in body and mind it gradually becomes our second nature and this is the way we function in life.
A person can have a very flexible and strong body but if her mind is scattered, she suffers from mental instability and can’t concentrate her attention, she is a beginner. Another person can have a weak and tight body or even suffer from injuries but her attention is undisturbed, she can stay with her awareness at the present moment she is advanced in Hatha Yoga. Unfortunately, this type of advancement can’t be captured on Instagram but you could tell, by your experience of joy that accompany this state, the reasonless, undisturbed happiness that follows the practice.
