在等式中插入段落

Question

如何在公式中插入段落。我需要能够在段落内换行。

\documentclass{article}

\usepackage{amsmath}

\begin{document}
        \begin{align*}
            y =& C_1e^{(3+2i)x} + C_2e^{(3-2i)x} \\
                     & \left\downarrow\rule{0cm}{1.5cm}\right.\quad\text{Insert text here with line breaks}\\
            y =& e^{3t}\left(A_1\cos 2t + A_2\sin 2t\right)
            \end{align*}
\end{document}

添加\parbox：

\documentclass{article}

\usepackage{amsmath}

\begin{document}
        \begin{align*}
            y =& C_1e^{(3+2i)x} + C_2e^{(3-2i)x} \\
                     & \left\downarrow\rule{0cm}{1.5cm}\right.\quad\text{%
            \parbox{2.5cm}{Insert text here with line breaks}}\\
            y =& e^{3t}\left(A_1\cos 2t + A_2\sin 2t\right)
            \end{align*}
\end{document}
