Human Psycology A person by appearence is single but his mind is always double - one is open and other is hidden. Every human being possesses two distinct types of minds. Generally, these two minds do not align with each other. The reason for this is that every individual has created and cultivated one mind for themselves and another for society. An open social mindedness is develpned as a way to demonstrate concern for the community's well-being—ensuring one is not ostracized while living within it. Usually the open mindedness is exposed when the person is in a group or among public with an aim that the other will think high about him when this persona is genuine, the individual is largely a good person, whereas when it is feigned, they tend to be somewhat malevolent. In contrast, the mind that contemplates self-interest while in solitude differs from this open social persona, effectively causing the individual to don a mask.The nature of these two minds of a person can be seen by throwing 500 rupee note in the street in which he passes by, if he is alone he may take the money and keep in his packet ,it is done as said by his own and hidden mind. If he is walking along with few unknown public, he will pretend by searching the money loser ultimately he will put it in a hundi in temple. These two different minds determines the real character of a person. A person cannot be 100 % good or 100 % bad The percentage of mixing of these two minds measures how good or bad a person is.
