Krishna says in Gita that all the activities are done by the body and the soul does nothing. I find this statement hard to believe. We all know that without the soul, the body is nothing but a corpse. It's the soul's presence in our bodies which keeps us alive. So how can the body (the vehicle) do all the activities without the contribution of the driver (the soul)?
As far as i know, the soul under the spell of maya / prakriti, forgets it's higher eternal nature and thinks that he/she is only the body and this is how the soul does all the activities, by using the body as it's instrument. Correct me if i'm wrong.
Here's the Gita verse -
Chapter 13: Nature, the Enjoyer, and Consciousness
prakrtyaiva ca karmani kriyamanani sarvasah yah pasyati tathatmanam akartaram sa pasyati
One who can see that all activities are performed by the body, which > is created of material nature, and sees that the self does nothing, actually sees.
