Ignorance is a state that exists within humans and one who possesses it advances towards darkness, whereas one who keeps it away from himself reaches luminosity and acquires discernment and insight.
If a person chooses an incorrect path for himself and permits ignorance to guide him in his actions, he would be looked upon as a sinner and of the inmates of Hell. However, if he sets about on the correct path, and acts on the basis of knowledge and cognizance, he shall be of the delivered ones.
