16.189

解云：厭離段食作不淨觀者，以於意識觀行成，設人五識對境亦厭，是故五受亦能觀境過失。

It is explained: When one is disillusioned with material food and practices the contemplation of impurity, because this contemplative practice is perfected in mental consciousness, even if a person's five consciousnesses confront an object they also feel revulsion; therefore the five feelings can also contemplate the faults of objects.
