The problem with the loneliness I suffer is that the company of others has never been a cure for it.

The desolation of loneliness is terrible. Was I wise? Perhaps not, but it seemed as though anything else was impossible.

The cure for loneliness is solitude.

Loneliness is not cured by human company. Loneliness is cured by contact with reality.

To experience the loneliness of soul is the hardest thing in the world.

Solitude was my only consolation - deep, dark, deathlike solitude.

A person, individually, is always terribly lonely forever and ever.

If one's different, one's bound to be lonely.

…nothing remained but loneliness and grief…

The worst kind of loneliness gripped him. The kind you feel alongside another person.

Man ordinarily lives in loneliness. To avoid loneliness, he creates all kinds of relationships, friendships, organizations, political parties, religions and what not. But the basic thing is that he is very much afraid of being lonely. Loneliness is a black hole, a darkness, a frightening negative state almost like death … as if you are being swallowed by death itself. To avoid it, you run out and fall into anybody, just to hold somebody’s hand, to feel that you are not lonely… Nothing hurts more than loneliness.
But the trouble is, any relationship that arises out of the fear of being lonely is not going to be a blissful experience, because the other is also joining you out of fear. You both call it love. You are both deceiving yourself and the other. It is simply fear, and fear can never be the source of love. Only those who love are absolutely fearless; only those who love are able to be alone, joyously, whose need for the other has disappeared, who are sufficient unto themselves…

The day you decide that all these efforts are failures, that your loneliness has remained untouched by all your efforts, that is a great moment of understanding. Then only one thing remains: to see whether loneliness is such a thing that you should be afraid of, or if it is just your nature. Then rather than running out and away, you close your eyes and go in. Suddenly the night is over, and a new dawn … The loneliness transforms into aloneness.

Aloneness is your nature. You were born alone, you will die alone. And you are living alone without understanding it, without being fully aware of it. You misunderstand aloneness as loneliness; it is simply a misunderstanding. You are sufficient unto yourself.

The worst loneliness is to not be comfortable with yourself.

Loneliness as a situation can be corrected, but as a state of mind it is an incurable illness.

A sense of utter loneliness—loneliness inevitable, crushing, eternal, the loneliness of existence, encompassed by the infinite void of unconsciousness—enfolded him as a pall. Life lay like an incubus on his bosom. He shuddered at the thought that death might overlook him, and deny him its refuge.
