197.6

他心示現者，如彼心、如彼意、如彼識，彼應作如是念、不應作如是念、彼應作如是捨、彼應作如是身證住，是名他心示現。

When demonstrating others’ minds, [he would say] according to their thoughts, their thinking, and their awareness, “That is something that you should think,” “that isn’t something you should think,” “that is something you should abandon,” “that is something you should personally realize and abide in.” This was called the demonstration of others’ minds.
