„Once in one's life, for one mortal moment, one must make a grab for immortality; if not, one has not lived“

Man büßt es theuer, unsterblich zu sein: man stirbt dafür mehrere Male bei Lebzeiten.

General sources
Kontext: Life becomes meaningful and all activities are purposeful only on the basis of faith in the enduring reality. … The greatest romance possible in life is to discover this Eternal Reality in the midst of infinite change. Once, one has experienced this, one sees oneself in everything that lives, one recognises all of life as his life, everybody's interests as his own. One is no longer bound by habits of the past, no longer swayed by the hopes of the future — One lives in and enjoys each present moment to the full. There is no greater romance in life than this adventure in realization.

Letter to Claude Hochet (Summer 1800), quoted in J. Christopher Herold, Mistress to an Age: A Life of Madame de Staël (New York: Grove Press, 1958), p. 223
Herold comments: "Her decision was emphatically in favor of suffering, which after all was a pleasure compared to boredom." (p. 224)
The actual quotation is from a letter from Mme de Staël to Claude Hochet dated October 1, 1800 : «Il faut choisir dans la vie entre l’ennui et le tourment : je donne l’un et l’hiver l’autre» (Germaine de Staël, Correspondance générale. Tome IV. Première partie. Du directoire au Consulat. 1er décembre 1796-15 décembre 1800, texte établi et présenté par Béatrice W.

What I Believe (1938)
Kontext: One must be fond of people and trust them if one is not to make a mess of life, and it is therefore essential that they should not let one down. They often do. The moral of which is that I must, myself, be as reliable as possible, and this I try to be. But reliability is not a matter of contract — that is the main difference between the world of personal relationships and the world of business relationships. It is a matter for the heart, which signs no documents. In other words, reliability is impossible unless there is a natural warmth. Most men possess this warmth, though they often have bad luck and get chilled. Most of them, even when they are politicians, want to keep faith. And one can, at all events, show one's own little light here, one's own poor little trembling flame, with the knowledge that it is not the only light that is shining in the darkness, and not the only one which the darkness does not comprehend.

Vol. I, The Way of Illumination, Section I - The Way of Illumination, Part III : The Sufi.
The Spiritual Message of Hazrat Inayat Khan
Kontext: The religion of the Sufi is not separate from the religions of the world. People have fought in vain about the names and lives of their saviors, and have named their religions after the name of their savior, instead of uniting with each other in the truth that is taught. This truth can be traced in all religions, whether one community calls another pagan or infidel or heathen. Such persons claim that theirs is the only scripture, and their place of worship the only abode of God. Sufism is a name applied to a certain philosophy by those who do not accept the philosophy; hence it cannot really be described as a religion; it contains a religion but is not itself a religion. Sufism is a religion if one wishes to learn religion from it. But it is beyond religion, for it is the light, the sustenance of every soul, raising the mortal being to immortality.
