so why would a person who can have endless happiness not choose it ?
the current thinking is... the feelings of happiness we experience are a
mild form of the intense feelings of happiness that are experienced in
built into the state of mind that made the heavenly state is the
orientation or understanding which takes into account the need to avoid
motions which can't be reciprocated (giving back in equal measure that
which has been given)
as an example... if you were moving forward on a perfectly level and
perfectly smooth bit of ice 100's of miles long you would need to take
care that you didn't suddenly change direction and move into the path
of someone else moving at a different speed
