Yoga is becoming popular recently and equally becoming very commercialised and competitive. There is too much emphasis on physical flexibility with impossible and intimidating postures to demonstrate physical flexibility and superiority. Such super-flexibility is not necessary for the well-being of body or mind.
The mind that is stuck at the physical level becomes a hindrance in your progress. You can spend time better pursuing higher aspects of yoga than only focusing on physical flexibility alone.
In the true practise of yoga, body is respected, as it houses the Higher Consciousness. Yet, a greater emphasis is placed on the well-being of mind and other hidden gifts of human existence since the body is only a wrapping paper.
The practise of yoga in its true spirit is neither competitive nor judgemental. Yoga is a multidimensional practise and except for the asanas , no other element of it can be physically measured.
The essential elements of yoga:
Mental peace and calmness
Level of your awareness
Love and compassion for others
The degree and depth of your connection with the inner self
Are there any scales to measure this in you?
Though these elements of yoga cannot be quantified, you can observe a vast change within yourself when you attend the Art of Living Yoga Programmes, such as the Sri Sri Yoga courses, which cater to enriching all the essential elements of yoga to give you a complete yoga experience.
Without the practise of other elements, practise of asanas alone which is Hatha yoga cannot be called the practise of yoga.
