When we see or experience an object, we think about it. Our language is a reflection of our thoughts. Whatever we think, we express it in words. Our brain, based on what our senses feel, see and hear, assesses the objects seen and heard on the basis of the power of our thoughts and expresses them through words. The ability to assess the thoughts of all the people of the world is different. This is why 10 people feel and see the same object in the same way, but the thoughts of those 10 people are different about that object because they assess that object in their mind according to their thoughts. This is why despite having the same object and the same language, there is a difference in the words of all the ten people. Thought is a process going on in the human brain. Thoughts are neither affected by the environment nor are they independent of the environment. Thoughts are related to knowledge nor ignorance. Thoughts are related to life. A person's thoughts keep changing with his life. As he lives his life, so does his life change. As experience increases, his thoughts begin to change. This is why the thoughts of an elderly person contain his entire life experience, which acts as a guide for other individuals. The human society in which we live today, the foundation of this human society must have been laid by an elderly person with his deep thoughts at some point of time because only an elderly person can give such great thoughts from his experience. Whenever any calamity has come in the human society, it has been resolved by an elderly person. Even today, if there is a problem in the family, it is the elder of the family who resolves it. In the administration of every country, more respect and important positions are given to those people who have more experience of work and have independent thoughts. Even less educated people sometimes say such things that great scholars are unable to say.
