In chapter 12 of the Bhagavad Gita, Arjun asked Shree Krishna-which is best path, Bhakti or Gyan? Shree Krishna answered him by declaring Bhakti to be the best and simplest path to attain God. Swami Mukundananda further takes the explanation ahead and says there are two types of actions- mechanical and emotional. A 3-year old child doing pranam to Swamiji when insisted by his parent is the example of the mechanical action. The child doesn't know who is Swamiji, what does doing pranam mean and why he needs to do it. He does it mechanically because his parents have taught him to do so. This is not bad but not enough. It will not free us from the bondage of birth and death. For liberation and attainment of Divine love, we need to rise above the mechanical-physical drill. Thus Shree Krishna says, Gyan is above such physical devotion. Dhyan is above Gyan. Renouncing the fruit of action is above Gyan and Dhyan.
