Justify text in other language (Hindi)

Hello,

Would you please tell me how should I justify text in my website’s pages? The pages of the website are in language other than English – they’re in Hindi language. To support this language, I’m using Polylang plugin and Text Editor (not HTML Editor).

Here’s the link:
