Get the field data in email body whenever user creates content, I want to get the few fields data of content in the mail body and trigger mail,, as of now i have created rule to trigger mail with text comparison condition for specific field.   

ex: I have content with user id, pancard Id fields etc,now i want to get this content field data in mail body and send mail to user.
Depending on the kind of rule event which I expect to be "When a new content is created" in your case.

When you choose action of rule as "send email" it allows you to use tokens, as declared by token modules. You will see the node tokens for the field as well, use it and those will get automatically replaced.
