Who does not like rewards? But the rewards which give us joy and delights keep changing. They keep changing with what we have. They keep changing with our age. They keep changing based on our riches or poverty. They change based on what we desire and want. They keep changing based on what we value. They change based on our perception. They change based on what we know. They change based on whom we have given Lordship of our lives to. And many other factors.
