Asana - the third limb of yoga

Asana is the third (out of eight) limb of yoga.
In the very old days Asana meant "to seat", probably  in meditation posture
With time it turned to mean a body posture, and then, the physical practice of yoga.

"Sthira sukham asanam" Poture should be steady and comfortable.
The Yoga Sutras of Patanjali, 2.46 Bryant's translation.

According the Scriptures Asana should be practiced because:
1.  It prepares the body to be able to stay in seating meditation posture for a long time.
2.  It creates "tapas", heat that purify body and mind.
3.  It loses all awareness of the sensation of the body. the mind can now be focused in meditation  without being distracted by the body.

Yama - the first limb of Yoga

The Yama is the first (out of eight)  limb of yoga.
Practicing the Yamas helps to channel the energies of the organs of action  in the right direction.
It contains five moral and ethical commandments:

1.  Ahimsa - nonviolence. 
When non violence in speech, thought  or action is established, one's aggressive nature is relinquished and others abandon hostility in one's presence. 
 The Yoga Sutras of Patanjali, 2.35, Iyengar's translation. 
2.  Satya - truthfulness
When the sadhaka is firmly established in the practice of truth, his words become so potent that whatever he says come to realization.
 The Yoga Sutras of Patanjali, 2.36, Iyengar's translation. 
3.  Asteya - non stealing
When abstention from stealing is firmly established, precious jewels come. 
The Yoga Sutras of Patanjali, 2.37, Iyengar's translation.
4.  Brahmacarya - Chastity, continence
When one is firmly established in continence, knowledge, vigour, valour and energy flow to him.  
The Yoga Sutras of Patanjali, 2.38, Iyengar's translation.
5.  Aparigraha - non grasping 
Knowledge of past and future lives unfolds when one is free from greed for possession.  
The Yoga Sutras of Patanjali, 2.39, Iyengar's translation.

Is there any contradiction between them?
