The arena of management and religion have been an important and inseparable part of human life since the beginning of time. Both had and still have their own importance and somewhere they get interlinked at times. Religion and Art of Management both teach a person to manage: Religion teaches to manage oneself spiritually whereas by using the Art of Management, a person manages his day to day life, socially as well as economically. Life of Guru Nanak Dev provides a lot of material to learn from. The decisions he took, the path he followed to make his ideology reach the masses, and that too only by discussions and debates, the power he displayed to stand strong in the face of competition, and against those who were erroneous in their actions. All these provide a platform for a deep research and study. Studying the incidents from his life in combination of the management tools can help the upcoming managers to manage their professional lives with ethical business practices while at the same time achieving great heights for their career and their organizations.
