Lyric discussion by Teabeard 

Cover art for Inside lyrics by Toad the Wet Sprocket

It is definitely about something inside (just as the title suggests), but whatever it is is deep and buried. I agree completely with Moonlapse Vertigo that this is about being weighed down by self-righteousness, anger, and so forth. What is buried deep within is forgiveness and love and until it comes out this individual will never be able to move forward.

This is an excellent song, one of the best by Toad. Its a shame it isn't well known.
