[Bhagavad Gita 3.5]

Implied Meaning: No human at any time can live without work even for a moment because the whole mankind is forced to do work under the compulsion of the gunas* (properties) of the nature.

*There are three types of gunas; tamasic which is about inertia, rajasic which is about desires and sattvic which is about intellect. Everybody has these three gunas in different proportion.
