Yes, flexibility of body and physical perfection for Yogasana is important. However more important is the state of your mind, Meditative mind. Your flexibility might be excellent but if your mind is not attentive, you are merely doing some physical exercise, not Yoga.

Yoga allows you to find an inner peace that is not ruffled and riled by the endless stresses and struggles of life.

The sleeping tortoise takes all its limbs into its carapace. So does the yogi: going back into himself he does not see anything worldly any longer, he makes peace in himself.

It took me whole decades to appreciate the depth and true value of yoga. Sacred texts supported my discoveries, but it was not they that signposted the way. What I learned through yoga, I found out through yoga.

The body is the prop for the soul. So why not let the body be propped by a wall or a block?

I am old, and death inevitably approaches. But both birth and death are beyond the will of a human being. They are not my domain. I do not think about it. Yoga has taught me to think of only working to live a useful life...I will never stop learning, and it have tried to share some lessons with you. I do pray that my ending will be your beginning. The great rewards and the countless blessings of a life spent following the Inward Journey await you.

The whole thrust of yogic philosophical and scientific inquiry has therefore been to examine the nature of being, with a view to learning to respond to the stresses of life without so many tremors and troubles.
