Написать отзыв о стихотворении благовест толстой.

Среди дубравы
Блестит крестами
Храм пятиглавый
С колоколами.

Их звон призывный
Через могилы
Гудит так дивно
И так уныло!

К себе он тянет
Неодолимо,
Зовет и манит
Он в край родимый,

В край благодатный,
Забытый мною,-
И, непонятной
Томим тоскою,

Молюсь, и каюсь я,
И плачу снова,
И отрекаюсь я
От дела злого;

Далеко странствуя
Мечтой чудесною,
Через пространства я
Лечу небесные,

И сердце радостно
Дрожит и тает,
Пока звон благостный
Не замирает...
