Yes, you example and some testing shows, that it isn't tex.print,
but \directlua seems to remove \par if it has its original meaning.

  \def\par{bar}
  \directlua{

  foo = 1}

Then Lua sees "barfoo = 1".

Something like the following should fix the OP's problem:

\begingroup
  \def\par{\endgraf}
  \directlua{
    text = [[
      This is a paragraph
      with some lines.

      This is another paragraph,
      separated from the first
      by a blank line. ]]
    tex.print(text)
  }
\endgroup
