瑜伽論記 16.63

16.63

問：若未至有喜何故不立答可動故者，問意如初靜慮有喜則立五支，未至地中既有喜受，何故不立支耶？

Question: Regarding the statement, "If there is joy in the unarrived [absorption], why is it not established [as a branch]? The reply is: Because it is movable": The meaning of the question is that just as in the first dhyāna, when there is joy, the five branches are established, since there is also the sensation of joy in the unarrived stage, why is it not established as a branch?
