Sharing power increases your power because of the respect you gain from your direct reports. However, as the text stated, you should never give up overall power on decisions. Giving full power to employees could ultimately backfire. A good way to increase one's power is to delegate responsibilities that an employee can gain from. Having employees start assisting and taking over tasks would further develop and enhance their skills and prepare them for additional responsibilities. By sharing the power....you build trust with team which in turn will make you a more effective manager and leader.
