If I have text between two align blocks, I lose the alignment. Is there an easy way to solve this?
\documentclass{article}
\usepackage[utf8]{inputenc}
\usepackage{amsmath}
\begin{document}
\begin{align}
a^2 &= b^3+c^3+d^3 \\
a^2+d^3+z^4 &= b^3+c^3+d^3
\end{align}
Some other text
\begin{align}
a^2 &= b^3+c^3+d^3+b^3+c^3+d^3
\end{align}
\end{document}
The equals are not aligned:

Some other text. If what you're planning is a whole bunch of paragraphs, then sure, there are other options, but please specify this as part of your request. Realistic examples would help. – Werner Aug 14 '18 at 18:59
