Hi Madhava,
Thank you for your question.
To include paragraph system component while creating a CQ page, you can follow as below:
Add the parsys component (one of the foundation components) to your content page component.
i) In CRXDE Lite, browse to /apps/mywebsite/components/contentpage, open the file center.jsp and locate the following line of code: <div>parsys</div>
ii) Replace that line of code with the following code, then save the changes: <cq:include path="par" resourceType="foundation/components/parsys" />
iii) In your browser, refresh the Products page. It now has the parsys component.
