Acharya Prashant explains the teaching of Lao Tzu, 'Do your work, then step back,' by highlighting how humans chronically fail to do so. He compares our behavior to a salesman who refuses to leave a customer's doorstep until payment is received, illustrating our constant demand for the fruits of our actions. This refusal to step back creates a cycle of waiting, which in turn creates time, future, and hope. He asserts that there is no suffering worse than hope and expectation, as they keep an individual trapped in a state of chronic dissatisfaction and mental torture.
