When we analyze the passions that work in our life, we find that passions change according to circumstances and events. If fear and terror are created in the environment, then people live a life of fear. In contrast, if there is an environment of bravery and valour, then people do not get sick. Similarly, if the environment is one of negligence, indolence, and carelessness, then the people who live in this environment are also lazy and negligent. But if negligence and laziness are removed from the environment, then people become practical and perform heroic deeds by using their will.
