Bhagwad Gita says that expectation is evil & cause of all our misery. Epictetus talks about things in your control is your consciousness.
We are living in a society trapped with materialistic needs and making everyone happy around us. Marriage and relationships with loved ones have turned into a transaction. We have gone into undefined wants and needs causing enormous pain ourselves.
What actions of others will make us sad, unhappy, or pleasureful: even we don’t know. The expectation of respect, reciprocity, power, and love from others makes us sicker.
