Pls help: Including hypertext within our posts

I want to add hypertext in my post without typing in the URL as part of the text.

For example I want to direct "a kindred soul" in the following text to be linked to http://mindblur.wordpress.com without displaying this URL.

"my journey through life has been eased by a kindred soul from far far away.."

Can someone explain how this can be achieved?

Thanks in advance :)
