aśaikṣa. No longer learning, beyond study, the state of arhatship, the fourth of the śrāvaka stages; the preceding three stages requiring study; there are nine grades of arhats who have completed their course of learning.

A Dictionary of Chinese Buddhist Terms, William Edward Soothill and Lewis Hodous

在聲聞乘四果中，前三果為有學，第四果阿羅漢為無學。有學是還要上進修學的意思，無學就是學道圓滿不更修學的意思。

陳義孝編, 竺摩法師鑑定, 《佛學常見辭彙》

(aśaikṣa). "No-more-learning;" the stage at which one no longer needs religious training, as opposed to 有學 (youxue). Another name for an arhat 阿羅漢 who has completed the course of practice. One who has attained the state of arhat, has already abandoned all defilement, so there remains nothing to learn and practice. The last of the four stages 四果 of the śrāvaka path.

指應當修學的都已親身體證者，即指「阿羅漢」，參看「阿羅漢」。
