Hell is the solitude of one who aimed to be absurdly self-sufficient.

Love is eternal. That is the first fundamental stone of my faith.
The second fundamental stone of my faith is the certainty that I am loved.
And the third is the certainty that that mysterious freedom we carry within us is given to us solely for the purpose of enabling us to respond to love with Love.
The dazzling beauty of freedom lies not in making us free from, but in making us free for. For the purpose of loving and being loved. No, hell is not other people! Hell is the loneliness of the one who sought to be absurdly self-sufficient.

(Abbé Pierre /Henri Grouès, August 5, 1912 – January 22, 2007/, Testament)
