“One who sees inaction in action, and action in inaction, is intelligent among men, and he is in the transcendental position, although engaged in all sorts of activities.” (Bhagavad Gita 4.18)

This is Karma Yoga, and the way I practice it (Work as Witness as opposed to Work for God) is like an informal do nothing meditation throughout the day. They dovetail very nicely and both also dovetail with the central message of Jnana Yoga.

Here's a good explanation of that verse from the Gita. https://youtu.be/n-SUJ0Vwelk?t=1079
