Even a small hole can bring light into a dark room.When a room is closed from all sides and if you accidentally get trapped inside it, then the darkness and the panic of the closed room also reduces your ability to think. In such a situation, if there is strong light outside the room, then a small hole in the room will also bring a ray of hope to your mind along with that light.
Well, this was an imaginary situation, which may not happen to everyone, but a similar situation arises when we are upset due to some reason and there is no hope around us, even then our mind does not work and we panic.
To remove the darkness of our mind, we have our conscience in the form of a hole that gives us a glimpse of the light from outside and binds our hopes so that we can get through difficult times easier. Therefore, no matter how bad the situation is, one should never lose his/her conscience.
