Context

“it is a cruel jest of Nature's, a flowering tree that bears no fruit. The thought of your lovely children goes through me like a knife. My life has grown narrower, while yours has expanded and shed its rays afar. The passion of love is essentially selfish, while motherhood widens the circle of our feelings. How well I felt this difference when I read your kind, tender letter! To see you thus living in three hearts roused my envy. Yes, you are happy; you have had wisdom to obey the laws of social life, whilst I stand outside, an alien.” source
