成唯識論演祕 3.720

問：此經迨今，總廷四譯，魏所譯本名《相續解脫》；梁、隨二本名《解節經》，今唐所譯名《解深密》，何乃不同？

Question: Up to the present day, there have been four translations of this sūtra in all. The version translated under the Wei was entitled Xiangxu jietuo (Continuity Liberation); the two versions of the Liang and Sui were entitled Jiejie jing (Untying the Knots Sūtra); now the translation of the Tang is entitled Jieshenmi (Explaining the Deep Secrets). Why are they different?
