I think Savasana is the most difficult asana among all asanas, because this need full concentration,awareness and control on your thinking and mind. This is not a simple asana, now the question come in Yoga why need Savasana?    
    我想挺尸式是所有体式中难度最高的，因为它要求注意力高度的集中，并且充分的控制你的大脑和思想。这不是一个简单的体式。下面的问题是瑜伽中为何需要挺尸式？

    During the class between other asana we need short Savasana to relax your all muscles and let your body again get ready for the next practice, and at the end of the class this is also very important, it can relax the whole body,mind and soul, and give you more internal energy and deep relaxation. So that's the main reason at the end of the class have Savasana for 10-15 minutes. The standard Savasana (Yoga Nidra or Yoga Deep Sleep) is for 1 hour.

     课堂上，不同体式间需要短暂的挺尸式来放松肌肉，并让身体为下一步的练习做好准备。最后，课程结束时的放松同样极为重要。通过挺尸式，不仅放松我们的身体大脑和精神，同时带来深度的放松，激发内部的能量。这就是在每节课程结束时我们安排10-15分钟瑜伽放松术原因。标准放松术为1小时。

    This is not so easy to relax completely , even if you are one who meditates, meditation is still an activity of engagement and distinct focus.

    要想完全放松，不是易事，即使对那些练习冥想的人来说，同样如此。冥想仍然是一种约束的活动，是典型的焦点集中。

    Savasana, as in any yoga posture, requires a certain focus. However unlike in meditation, rather than constantly directing attention to non-attention, shall we say, it is a practice of directing attention to complete and total relaxation.  An emptying from the scalp to the toes, from the spine to the internal organs.

    挺尸式，如同其它体式一样要求注意力集中。尽管不想冥想那样，但始终要求你从集中注意力到非集中状态的控制。换句话说，把你的注意力牵引到完全放松的状态。从头到脚，从外到内，完全清空。

    Allowing oneself to sink, heavy into the earth, easing all tension from muscles and joints, allowing the eyeballs to roll back in the sockets, the tongue to lay heavy at it’s root and the stomach and its organs to lower into the wall of the spine… oh, while remaining awake of course.

    让自己完全的下沉，陷入大地，驱除肌肉和关节里所有的紧张感，放松眼球，从根部放松舌头，让胃和其它的脏器放松，下沉……但是，保持清醒的状态。

    This pose is about letting go entirely.  Proper relaxation is integral to healthy functioning of mind and body providing a clarity of thought, aiding in judgment and decision making.   And in today’s hectic and increasingly stressful environment, at work and at home, true relaxation is difficult to come by and to many, difficult to justify. So In Yoga through Savasana u can completely relax from body,mind and soul.

    挺尸式令不少练习者陷入睡眠。 适当的放松完善身体的健康机能，令头脑清晰，决策明确。在现今充满压力的环境中，无论是工作场所还是回到家里，完全的放松似乎成了奢求。因此，通过瑜伽，让你的身心灵放松吧。
