＜自己甘心乐意主动去做而产生的喜悦＞是「根本的喜悦」，
因此那喜悦会持久。
The <joy that comes from you taking action on your own because you like it> is ‘fundamental joy,’ so it lasts for a long time.
＜自己不喜悦时，因对方让自己喜悦而产生的喜悦＞则如同喜剧演员逗你笑才笑一般，那是「勉强的笑容」，是「勉强的爱的喜悦和兴奋」。
The <joy that comes from another person when there is no joy from yourself> is like a ‘forced laugh’ when a comedian makes you laugh, and it is ‘forced joy and excitement of love.’
