泰云：有三種修定者，於一事中俱欲發轉變事，此二人勝解神通皆得自在，一欲作火，二欲作水，此二通非互相障礙，皆成此通，偏無勝者，故不相映奪。若有偏勝者相映奪者，即便一成一不成也，以無偏勝不相映奪，初皆不成，為作退不已，彼後無間，一於此事神通無礙如其所欲皆能轉變，第二神通便被障礙，何故初時二皆不成，後時一成一不成，此中所以云何應知。

Tai says: There are three kinds of practitioners of concentration. [When two] both wish to produce a transformation regarding the same object, both people have attained mastery in resolve and supernormal power. One wishes to make fire, and the second wishes to make water. These two supernormal powers do not obstruct each other; both have completed this supernormal power, and neither is superior, so they do not overpower each other. If one were superior and overpowered the other, then one would succeed and the other would fail. Because neither is superior and they do not overpower each other, initially neither succeeds. As [they continuously] strive without stopping, subsequently and immediately thereafter, one becomes unobstructed in supernormal power regarding this object and can transform it as desired, while the second's supernormal power is obstructed. Why is it that initially both fail, but later one succeeds and one fails? How should the reason for this be understood?
