Without sufficient wisdom, one cannot observe the manas through direct perception

While in the mother's womb, before the mind consciousness has arisen, what does the manas feel? Who can know? When unconscious, when in a vegetative state, what does the manas feel? Who can know? In the antarā-bhava, what does the manas feel? Who can know? After falling asleep, what does the manas feel? Who can know? At the moment of just waking up, what does the manas feel? Who can know? When encountering various events, what does the manas feel? Who can know? These dharmas are all very profound and subtle; if one's wisdom is insufficient, one cannot observe them through direct perception.
