I always think a lot about everything and the explanation I can give in this case is that there are messages that our subconscious perceives and then we return in actions or moods. Do you think so?
I also think that there is a message which is conveyed through these murals. I am amazed to read that these all murals have title like national hero's mural has "connection" title, "I have faith in destiny",a weird one "protection" and "my city". These title are based on the stories they had.
Yes, there are a lot of stories and also a lot of criticism in them. I like that the artists have expressed their emotions and their views through the paintings.
