若體位法以正確方式完成，身體的運動會非常平順，身體中會有輕盈的感覺心中會有解脫的感覺。若體位法讓人感覺沈重，那一定是錯的，你必須在全身傳達一種輕盈的感覺，你可以在想像中讓自己從身體的中心向外擴展，不要只想著舉起手臂，而要以身體的感受將手臂向外伸展；保持手臂靜止不動時，再想像將其智性擴展到身體之外，不要被當時不順的情境所影響，而感覺自己窄小、痛苦、受壓迫，要想像自己現在的狀態：既優雅 而 擴展。

一旦失去輕盈的感覺，我們的身體就會收縮，而身體一旦收縮，大腦就會變得沈重而遲鈍，你就什麼都看不見，也無法感知。

When an asana is done correctly, the body movements are smooth, and there is lightness in the body and freedom in the mind. When an asana is felt as being heavy, it is wrong. You must try to impart a feeling of lightness throughout your body. This can be achieved by mentally extending yourself outward from the center of your body, Think not just of raising your arms but of extending them outward in the physical sense, and when you are holding them still, think again of extending the intelligence by reaching still further away from your body. Do not think of yourself as a small, compressed, suffering thing. Think of yourself as graceful and expanding , no matter how unlikely it may seem at the time.

Whe we lose this lightness our bodies shrink. The moment the body shrinks, them brain becomes heavy and dull, and you see nothing. The doors of perception are close.
