Srimad Bhagavat Gita commentary chapter 18 verse 14

 Chapter 18 verse 14               

“The body, the doer, the various senses, the many kinds of efforts, and Divine Providence—these are the five factors of action.” 

Bhagwan elaborates on the five factors which enable all actions to be performed:

1.     Body

2.    Soul or Doer

3.    5 senses and 5 organs of actions

4.    Conscious effort

5.    Divine Grace

The first four are definitely needed to leverage field of action but divine grace is also needed to add the fertilizer to the soil for the land of action to be fertile and worthy of being tilled.
