Hi,

I would recommend that you use babel, as it is the official package for
language support and now has many more options than polyglossia.

You can
try this preamble (compiles in LuaLaTeX):

\documentclass{article}
\usepackage[english]{babel}
\usepackage{fontspec}
\newfontscript{Devanagari}{deva}
\babelprovide[onchar=ids fonts]{sanskrit-devanagari}
\babelfont[sanskrit-devanagari]{rm}{Noto Sans Devanagari}

With \babelprovide... there is no need to add a \selectlanguage or other
similar command. The problem with your example is that you need to put a
command to select the language before the Devanagari text, like
\selectlanguage{sanskrit}

Old expression goes like स्वस्ति सत्यं वचति (meaning 'Always tell the truth with positive vibes') where स्वस्ति means positive, सत्यं means truth and वचति means tell or speak out.

Best regards,

Juan Manuel
