What goes wrong in our search for Moksha?

Moksha - the state free from suffering. Humans have searched for this state all along. But their framework is only humans. Moksha is best understood by observing nature. The wild birds and animals. Even plants. They do not seek joy or suffering. They take what they need and get. All duties are done with great dedication to the best of their abilities. Nature is always in a state of nirvana.
