LaTeX indents paragraphs by default, except after section titles. How did you configure your document? –  Andrey Vihrov Feb 23 '12 at 10:03
I don't really understand what you're trying to do. Please add an example. –  Thorsten Feb 23 '12 at 10:03
Please add a minimum working example (MWE) that illustrates the problem you're experiencing. –  Mico Feb 23 '12 at 11:24
How are you ending your paragraphs? –  egreg Feb 23 '12 at 11:35

Paragraph indention is controled by the parameter \parindent. In most document classes it is set to a positive value so you should see indentations. If this is not the case you can set this parameter in the document preamble to whatever value you wish, e.g.

\setlength\parindent{24pt}

Of course, a requirement is that you mark up your paragraphs: a paragraph ends by either a blank line or by the command \par. If you instead just used \\you have directed LaTeX to start a new line but not a new paragraph.

Thanks for your suggestion its working good. –  pavani Feb 24 '12 at 9:10
Just one comment (also for @pavani). It is usually a good idea to define \parindent in terms of the type size. That way the indentation will scale if you change the size of the type. Bringhurst recommends indenting the paragraph by the same size as the type or the leading. So if you set the size using \fontsize{11pt}{13pt}\selectfont, you should use 11 or 13 pt. –  Marc van Dongen Feb 21 '13 at 19:34
1 em is another common length to use. Although I have noticed that a lot of american english texts seem to have a bigger indentation. It all varies... :) –  jonalv Mar 3 at 14:46
