In yogic philosophy we have three functional minds: the negative, or protective mind; the positive, or expansive mind; and the neutral, or meditative mind. All are important to us. The negative mind protects us. It gives us discernment. In our pros and cons list, it is the cons, where we see the possible negative consequences of an action. We use our negative mind all the time. It helps us wait until all cars are clear before crossing the street; it helps us not make fools of ourselves in social situations; it keeps us on task at work instead of on Facebook.
The positive mind is just as it sounds — it’s the part of us that focuses on the positive in a situation. In our pros and cons list, it's the pros. It also allows us to see the good in all, and be open to all the possibilities in our life. It’s where we draw our optimism, playfulness, and sense of humor.
Then there's the neutral mind. This is the place where we assimilate information from both the positive and negative minds and make a decision. It is in this space we can weigh pros and cons without being more attached to one side or another. This is the space we are acting from when we are following our dharma, or our true path in life. When we have a strong neutral mind, we act from intuition.
