Just as [you] feel tired after working a lot with ‘the body,’
you feel tired after thinking a lot with ‘the heart’ also because it has worked.
Among the things the heart does, there are things that make it most tired.
When a person thinks of the matters that make them worried, concerned,
and anxious, it is more tiring.
