A man does not attain exemption from action by not commencing action.
Nor even by renunciation is success acquired.

Source: Milind S. Pandit

One does not attain freedom from the bondage of Karma by merely abstaining from work. No one attains perfection by merely giving up work.

Source: The Bhagavad-Gita: The Sacred Song

Not by merely abstaining from work can one achieve freedom from reaction, nor by renunciation alone can one attain perfection.
