Fountain of truth

Inside my head the beast is on a leash, everyday we fight, sometimes i win, but more than often i lose. I found a peace within a cup of divine past. It seems to be the only thing which puts him to sleep. But when awoken, well, he is nothing more than a monster.. He loves nature, and i love games.. All he says is like a fountain of truth, he can seek into the mind of others and see their darkest secrets that comes like whispers in the night..
They follow him blindly, they know when he speaks, but he is always hidden in that dark corner of the mind.. When he is out, there is nothing but darkness around, but they know its always the truth.. While i always try to lie..
