Through love, through friendship, a heart lives more than one life.

The line appears in a diary entry dated December 27, 1922, where Nin reflects on receiving letters from her cousin and friend Eduardo Sánchez and how his connection eases the harshness of her own experiences.

Nin suggests that close bonds let a person emotionally participate in others’ joys and hardships, expanding one’s inner life beyond a single, isolated perspective.

Through love, through friendship, a heart lives more than one life and is made joyful or sorrowful by the experiences of many others.
