You certainly can. There are lots of directions you can go in, from working with the emotions to recognising emptiness. Check out my meditation links for my recommendations: http://danbartlett.co.uk/meditation/

I also run http://OpenSit.com which is a free meditation journal and global community, where you can share your practice and connect with others. It's open source too ^-^

You can read my meditation journal, including goofy entries from when I first started meditating 6 years ago, here: http://opensit.com/u/danbartlett
