If you claim that you are a Yogi, then you should have an undying smile on your face. I would say, that is the sign of a Yogi.
Yoga makes your emotions softer and more peaceful, and you blossom in your emotions.
It brings freedom in your expression and your thought patterns.
These are the real signs of Yoga. It is not just to do with the flexibility of the body. Of course, that too is a part of Yoga. The body becomes flexible, and the mind grows in faith and conviction. If all this happens, know that it is the gift of Yoga, and consider yourself as a Yogi.
Many people think of the eight limbs of Yoga as a step-wise process to go level by level. They think that one has to strive to become proficient in one level before ascending to the next. This is not really so.
I would say that all these eight limbs or aspects of Yoga are woven together and happen simultaneously. When a child is conceived in the womb, then all its organs are formed together. It is not that first the feet are formed and then the arms take shape.
No, it is not so.
All the limbs and organs develop together. This is why we must take all these eight aspects or limbs of Yoga together at every step. Only then can we experience the fullness and totality of Yoga, and can bring about an extraordinary transformation and experience in our life.
