Swiss Retreat 2019 Group Interviews 18 (4:55-6.30)
Yogi: I felt that my body fell asleep, but my mind was very alert at the end of the day. There was an initial feeling of sadness because I felt enormous amount of gratitude for the body when I saw the tiredness in the body.
Sayadaw: There is a question if the use of the word sadness is valid because there is an identification of a feeling with the word, and the word is giving the feeling that meaning.
To have a clear mind and the body is tired, and the mind feels sadness, maybe just call it a feeling and not name it sadness; not to assume right away that that is actually the emotion.
