這裡有一個常見的「錯誤觀念」：「在瑜伽修行一闕始，就要一起 練習體位法 跟 調息法。」

根據我 (B.K.S Iyengar) 的經驗, 如果一個初學者想把體位法練好，便不可能同時專注在呼吸上。 否則他將失去平衡感 及 體法位的深度。請先在體位法中保持穩定、靜止，再把有節奏的呼吸法引入。

身體動作的程度隨著不同的體位法而有所不同。
動作的幅度越小，肺部組織內的空間就越小，呼吸也將更短促。
動作的幅度越大，肺部的擴張就越大，呼吸也將更深。

當瑜伽調息法和體位法結合起來時，完美的體位法應該不被打擾。

所以，

除非已經掌握體位法，否則不要嚐試練習調息法

，練習者很快就會發現，當體位法練好了，身體自然就開始調息了。

There is a popular misconception that both asanas and pranayama should be practiced together from the time Yoga-sadhana is begun.

It is the author’s experience that if a novice attends to the perfection of the postures, be cannot concentrate on breathing. He loses balance and the depth of the asanas. Attain steadiness(sthirata) and stillness (achalata) in asanas before introducing rhythmic breathing techniques.

The range of bodily movement varies from posture to posture. The less the range of movement, the smaller will be the space in the lungs and the breathing pattern will be shorter.

The greater the range of bodily movement in asanas, the greater will be the lung capacity, and the deeper the breathing pattern.

When pranayama and asanas are done together, see that the perfect posture is not disturbed. Until the postures are perfected, do not attempt pranayama. One soon realizes that when asanas are well performed, pranayamic breathing automatically sets in.
