    Wie Alles Begann

    by: Baff

    Vertraut geleitet an den fremden Ort, ließ ich manches zurück, und bewegte mich fort.
    Ein Stück von dort war ein unbekanntes Ziel, das ich so nicht verfolgte, wie in
    einem Spiel waren die Regeln verschwommen, es gab nichts zu bekommen, es gab nichts
    zu gewinnen, ich ließ mich einfach spinnen, die Zeit verrinnen und sah mir nur zu,
    wie mir Fühler wuchsen, deren Grund warst du. Offen und heimlich, aufrecht und
    peinlich war der Zufall geplant, entstand so ein Land, das wir oft verließen, öfter
    aufeinander stießen, es bei Ahnungen beließen, die uns neues verhießen, deine
    Gedanken, die konnten nicht klärn, wer gewinnt. Unser Traum fand die Worte nicht,
    die er verdient, doch fand die Neugier ihren eigenen Lohn, und bahnte sich Wege im
    Flüsterton.
    Wie alles begann, kommt mir dann und wann in den Sinn,
    über tausend Mauern führte doch mein Gang zu dir hin.
    Was alles geschah, glänzt wieder wie Gold,
    Fortsetzung folgt.
    Wir liefen los nebeneinander einen schier endlosen Weg, im Wald der Stille die
    Hoffnung gesät und gespäht, worin sich der andre verrät, wohin der Pfad geht, wie
    die Prüfung gerät. Kühne Gefühle, tanzten nun auf der Bühne, im Keller der
    Zweisamkeit wurde es heller, so hell, dass das Augenlicht schreckte, versteckte
    Signale, die ich dir zum Leuchtfeuer erweckte. Verwebte Erwartung gesteigert,
    erweitert die Sinne, war uns an der Stelle der Schwelle der Zutritt verweigert, der
    Anfang vom Ende das Ende vom Ende und mit ihm die Wende.
    Wie alles begann, kommt mir dann und wann in den Sinn,
    über tausend Mauern führte doch mein Gang zu dir hin.
    Was alles geschah, glänzt wieder wie Gold,
    Fortsetzung folgt
    Die Sinne, die wurden uns neu geboren, verborgene Dinge verborgen geborgen. Der
    Morgen danach war ein Morgen davor, ein Endpunkt wurde zum glänzenden Tor. Die
    Eindrücke füllten uns unsere Seelen, verhüllte Gefühle warn nun anzusehen, freizügig
    zu stehlen aus unendlichem Schatz - unsre Heimat nahm Platz.
