+'<pre>Измеряются грустью и чашками чая
+Безымянные, кроткие, зимние дни.
+Проживаешь мгновения, не замечая,
+Как бесследно теряются в прошлом они.
+
+Покрывает надежды обманчивый иней,
+Запотевшая память подобна окну.
+Растворяется контур реальности синей:
+Над экраном холодным и ясным усну.
+
+Утомлен безучастностью, сентиментален,
+Погружаюсь, запутавшись, в тихую тьму.
+А приснятся весенние язвы проталин
+И снега, равнодушны к концу своему.
+
+И покажется, будто неловко ступаю
+По сулящему гибель лукавому льду,
+Приближаюсь безвольно к незримому краю,
+Безучастно забвения смертного жду.
+
+Обреченность души молодой беспричинна,
+И мечты, и стремления сердца смешны.
+Неизбежно и близко маячит кончина,
+Обещая обители вечной весны.
+
+А былого сомнения ныне убоги,
+Поглотила пучина загробной реки;
+Мысли канули в тени последней дороги.
+Берега колдовской глубины далеки.
+
+Не внимая молитвам, судьба непреклонна,
+И слова, и молчание тщетны, пусты,
+Но зовут перезвоны миров Авалона
+Сквозь слепую завесу могильной черты.
+
+Промелькнуло знамение в зыби туманной,
+Воплощение обетованной земли.
+Кровоточит сознание призрачной раной.
+Рассеченную веру, Харон, исцели!
+
+На морозе растрескалась черная лодка,
+Перевозчик не тронет стремнину веслом.
+Изменилась от боли и страха походка:
+Не устанешь терзаться, скорбеть о былом.
+
+Разрывается грудь от печали железной,
+Утянуло уныние душу на дно.
+Беспредельная пропасть зияющей бездной
+Констатирует факт: умереть суждено.
+
+Принимаю жестокую истину эту.
+Под ногами ни твердь, но крошащийся наст.
+Пересечь пожелавший замерзшую Лету
+Неизбежно бесценное стражу отдаст.
+
+Проседает поверхность, ломаясь и тая,
+Увлекаясь течением мертвой воды,
+И тасует агония льды, как живая,
+И надежды безлики и сердцу чужды.
+
+На сминаемой глади нельзя схорониться,
+Настигает невидимый ужас. Фантом
+Беспощаден. Аида владений граница
+Искаверкала личность в тумане густом.
+
+Просыпаюсь, но кровь под висками грохочет,
+Что увидел в зловещем, пророческом сне.
+И дрожу, возвратившийся первопроходчик,
+Почему темнота ухмыляется мне?
+
+Поднимусь, в запыленное зеркало гляну,
+Не поверю, что нет в волосах седины.
+Удивленный открытому в духе изъяну,
+Осознаю, подобные обречены.
+
+Не бывает беспечна дорога поэта,
+И печаль неотступная бдит за спиной.
+Угнетает суровая истина эта.
+Почему безучастность любезна со мной?
+
+Очарован иллюзией, горечью болен,
+За словами под землю бреду в глубину.
+В лабиринтах блуждаю заброшенных штолен
+И ищу драгоценную правду одну.
+
+И в прорубленных поиском чьим-то пещерах
+Затеряюсь: обманка, сомнения, ложь.
+А в рассветных, неискренних сумерках серых
+На умершего в зеркале старом похож.
+
+Бесполезен желанием я. Одноразов
+И порыв, и поэзии выкрик немой.
+Принимаю стекляшки за груды алмазов.
+Одиссей никогда не вернется домой.
+
+Помню Данте и вечный огонь Одиссею,
+И правдивый, бесплотный, печальный язык.
+Опереться на слабую веру не смею,
+К безысходности мрачной за годы привык.
+
+Не боюсь очевидной угрозы обвала,
+Не боюсь нависающей тяжести гор.
+Равнодушная память, чадя, истлевала.
+Неужели конец однозначен и скор?
+
+Умываюсь, покинув недвижность постели,
+Отвечает насмешкой безмолвие глаз.
+А секунды, минуты, недели летели.
+Поклянусь измениться единственный раз.
+
+И слезами обет приношу перед Богом,
+Не терять ни мгновения, миг не терять.
+На пути разрушения скользком, пологом
+Не могу, покатившись, подняться опять.
+
+Поклонюсь утешающим, строгим иконам,
+И молитва развеет гнетущую тьму.
+И прощенный, служивший делам беззаконным,
+Не надеюсь тщеславно спастись самому.
+
+На восходе сугроб переливчат и розов,
+И затейлив узор приукрасил окно.
+Неужели с уходом кристальных морозов
+Полотно белотканное обречено?
+
+Опалив чистоту, молодое светило
+Прожигает сияющий кров белизны,
+А снежинки в бесплодную грязь превратило.
+Обтекают деревья угрюмы, темны.
+
+Почему разрушения ярость воспета?
+Сожаления вязки, сугубы, остры.
+Разлилась половодьем забвения Лета,
+Разделяя потоком зеркальным миры.
+
+А тлетворная оттепель жизни хлопочет,
+Умирает в смирении зимний покой.
+Вырываются листья из лопнувших почек,
+И весна торжествует в капели слепой.</pre>');
