Much depends on your attitude. If you are filled with negative judgment and anger, then you will feel separate from other people. You will feel lonely. But if you have an open heart and are filled with trust and friendship, even if you are physically alone, even living a hermit’s life, you will never feel lonely.

— Dalai Lama in The Book of Joy, Avery, Ch. Loneliness: No Need for Introduction, p. 129, 2016
