One child says she loves chocolates. The other immediately responds saying she hates them. Why these opposing feelings towards the same object, in this case, a chocolate? Where do these children learn what to like and what to hate? Who taught them these?
Adults teach and children learn. Adults act and children learn deeper and faster. Yes, that’s the truth. Every time a child sees their well wishers do something, it makes an impression on their minds. They learn that this is right or wrong and this creates a deep impression on their minds, which almost never changes. The problem is not in learning that a particular object is good or bad, and should be liked or hated. The problem turns into the bigger learning that we must learn to sort things into two compartments – that which we like and those that we hate. As children grow up, you can see these impressions taking enormous forms even while in school. It is not uncommon for us to hear children say, they like someone and they hate someone; someone is on their friend list and there are a few on the enemy list! Can you imagine small primary school children talking about enemies?
This grows and becomes a permanent feature in almost every adult. They all (including all of us) have likes and dislikes. We have them with foods, clothes, music, books, and more importantly people. This division is simply a figment of imagination. Just like the chocolate in the case of the children we discussed in the beginning, the goodness / badness are both not in the object (chocolate) in their case. Similarly as we grow up, this lack of understanding makes us feel that our likes and dislikes are always in the objects and beings around us. Hence we get affected by the nature and actions of the objects and beings that we come in contact with. Either we are happy that they align to our worldviews and like them or we are unhappy that they are not the way we want them to be, and hence dislike them. This constant stream of likes and dislikes makes us happy and sad alternately. We are not even aware that it is our misunderstanding which is actually causing this constant change in our state of mind. If we even get a doubt, we can reach out to philosophy to help us understand how to start walking out of our problem. If we do, our life becomes more peaceful. Vedanta is one such school of philosophy that explains this ignorance.
