Si realmente existe un poder oculto que tan traidoramente hunde sus garras en nuestro interior para cogernos y arrastrarnos a un camino peligroso que habríamos evitado, si tal fuerza existe, debe doblegarse ante nosotros mismos, pues sólo así ganará nuestra confianza y un lugar en nuestro corazón, lugar que necesita para realizar su obra. Si tenemos la suficiente firmeza, el valor necesario para reconocer el camino hacia el que deben conducirnos nuestra vocación y nuestras inclinaciones, para caminar con paso tranquilo, nuestro enemigo interior perecerá en los vanos esfuerzos que haga por ilusionarnos. También es cierto, añade Lotario, que la tenebrosa presencia a la que nos entregamos, crea con frecuencia en nosotros imágenes tan atrayentes que nosotros mismos producimos el engaño que nos consume. Es el fantasma de nuestro propio Yo cuya influencia mueve nuestra alma y nos sumerge en el infierno o nos conduce al cielo. ¡Te das cuenta, querido Nataniel! Mi hermano y yo hemos hablado de oscuras fuerzas y poderes que a mí, después de haber escrito, no sin esfuerzo, lo más importante, se me aparecen sosegadas, profundas. Las últimas palabras de Lotario no las entiendo del todo bien, sólo intuyo lo que piensa, y sin embargo, me parece rigurosamente cierto. Te lo suplico, aparta de tu pensamiento al odioso abogado Coppelius y al vendedor de barómetros Coppola. Convéncete de que esas extrañas figuras no tienen influencia sobre ti. Sólo la creencia en su poder enemigo las vuelve enemigas. Si cada línea de tu carta no expresara la profunda exaltación de tu espíritu, si el estado de tu alma no afligiera mi corazón, podría bromear sobre tu Hombre de Arena y tu abogado alquimista. ¡Alégrate! Me he prometido estar a tu lado como un ángel guardián y arrojar al odioso Coppola de una loca carcajada si viniera a turbar tu sueño. No le temo en absoluto, ni a él ni a sus horribles manos que no podrían estropearme las golosinas ni arrojarme arena a los ojos.
If there is a dark power, which with such enmity and treachery lays a thread within us, by which it holds us fast, and draws us along a path of peril and destruction, which we should not otherwise have trod; if, I say, there is such a power, it must form itself within us, or from ourselves; indeed, become identical with ourselves, for it is only in this condition that we can believe in it, and grant it the room which it requires, to accomplish its secret work. Now, if we have a mind, which is sufficiently firm, sufficiently strengthened by cheerful life, always to recognise this strange hostile operation as such, and calmly to follow the path which belongs to our inclination and calling, then will the dark power fail in its attempt to gain a power, that shall be a reflection of ourselves. Lothaire adds that it is certain, that the dark physical power, if of our own accord, we have yielded ourselves up to it, often draws within us some strange form, which the external world has thrown in our way, so that we ourselves kindle the spirit, which, as we in our strange delusion believe, speaks to us in that form. It is the phantom of our own selves, the close relationship with which, and its deep operation on our mind casts us into hell, or transports us into heaven. You see, dear Nathaniel, that I and my brother Lothaire have freely given our opinion on the subject of dark powers, which subject, now I find I have not been able to write down the chief part without trouble, appears to me somewhat deep. Lothaire’s last words I do not quite comprehend. I can only suspect what he means, and yet I feel as if it were all very true. I beg of you, get the ugly advocate, Coppelius, and the barometer-seller, Giuseppe Coppola, quite out of your head. Be convinced that these strange fears have no power over you, and that it is only a belief in their hostile influence that can make them hostile in reality. If the great excitement of your mind did not speak from every line of your letter, if your situation did not give me the deepest pain, I could joke about the Sandman-Advocate, and the barometer-seller, Coppelius. Be cheerful, I have determined to appear before you as your guardian-spirit, and if the ugly Coppelius takes it in his head to annoy you in your dreams, to scare him away with loud peals of laughter. I am not a bit afraid of him nor of his disgusting hands; he shall neither spoil my sweetmeats as an advocate, nor my eyes as a sandman.
