Pranayama is not a simple practice, need to be very careful while practicing. Wrong practice can leads so many diseases and can be harmful for your body.
         呼吸控制不是简单的练习, 务必多加注意. 错误的练习可能导致身体的伤害和疾病.

          Patanjali also wrote in the Yoga Sutra that moving from asana to pranayama is a big step. He warned that we must build enough strength and stability in the body and nervous system through our asana practice first, in order to withstand the increase in energy flow that pranayama generates. He  said first become a Master in Asana then take step in Pranayama.
        帕坦伽利在<瑜伽经>里写道, 从体位到呼吸控制是一个很高的台阶. 他告诫, 首先我们必须通过体位练习构筑身体力量和神经系统的稳定性, 在此基础上才能承受呼吸控制引起的能量流动. 帕坦伽利说,首先精通体位,然后涉足呼吸控制法.

          Pranayama is an advanced practice. It was only after many years of asana practice that Iyengar says he slowly began to build a pranayama practice. It took him many more years and great effort to sustain it. He didn't have the guidance of a teacher and made all the mistakes that Patanjali warned against. Because making these mistakes can be quite harmful, Iyengar advises that if you want to practice pranayama, you should do so only if you have a teacher with whom to work.
          呼吸控制法是一项高级的练习. 艾杨格说,他在多年的体位练习后才开始构建呼吸控制法的练习. 而且他花费的更长的时间和精力坚持呼吸法的练习. 没有老师的引导, 所以他经历了所有帕坦伽利提醒的可能出现的错误. 因为所有这些错误会导致身体的伤害,所以艾杨格建议如果你想练习呼吸控制法, 你只能跟随老师一起进行.

         Iyengar also cautions that if at any time during the practice of pranayama you experience pain in the head or tension in your temples, it means that you are initiating the breath from your brain, not your lungs. If this happens, return to normal breathing and relax.
        艾杨格提醒练习者,在呼吸控制法的练习中如果你感到头痛或紧张, 那可能意味着你牵动了大脑呼吸,而不是肺部. 发生这种情况时, 需回到正常呼吸.
