accessing hidden service

[bishneet]

I want to access a hidden service but when I edit torrc to give HiddenServiceDir as $HOME/my_dir/hidden_service, I can't get hostname over there as I get the error

Mar 13 14:11:22.549 [notice] Tor 0.2.1.30 opening log file.
Mar 13 14:11:22.550 [warn] /home/bishneet/tor/hidden_service/ is not owned by this user (debian-tor, 115) but by root (0). Perhaps you are running Tor as the wrong user?
Mar 13 14:11:22.550 [warn] Error loading rendezvous service keys
Mar 13 14:11:22.550 [err] set_options(): Bug: Acting on config options left us in a broken state. Dying.

So any solution?
