27.155

「他心智類至加占相成」者，釋第三、第四句。他心智類總有四種，前三如上，謂修、生、呪，又加占相。占謂占卜，相謂覩相能知他心。夫他心智知他心上一別相用，行相微細難可知故，非藥、業成。

"The varieties of the cognition of others' minds [...] up to with the addition of achievement through divination and signs": This explains the third and fourth lines. The varieties of the cognition of others' minds are four in total: the first three are as above, namely cultivation, birth, and spells, with the addition of divination and signs. Divination means prognosticating, and signs means knowing others' minds by observing physical signs. The cognition of others' minds knows a specific distinct functioning in another's mind; because its mode of activity is subtle and difficult to know, it is not achieved through medicine or karma.
