Simultaneous liberation. As distinguished from wisdom liberation 慧解脱， where one uses wisdom alone to accomplish freedom from the hindrances of affliction 烦恼障， one instead uses both wisdom and concentration to liberate oneself both from the hindrances of affliction， and the hindrances of liberation 解脱障. Due to this liberation， one attains the sama^dhi of total annihi^ation 灭尽定. One of the 二十七坚圣 and one of the nine no-more-learnings 九无学. ［瑜伽论 T 1579.30.832b18］
