長阿含經 18.p39

18.p39

“Some ascetics and priests examine it not using perception, don’t listen to gods or non-humans, nor is it their own or another’s examination themselves. After eliminating perception and examination, they attain a fixed state of samādhi. Examining another’s mind, they say, ‘Thus is your mind; thus is your mind.’ Such examination is true. This is the fourth examination.
