BG 14.10-12
Now Harmony prevaileth, having overpowered Motion and Inertia, O Bhârata; now Motion, having overpowered Harmony and Inertia; and now Inertia, having overpowered Harmony and Motion. When the wisdom-light streameth forth from all the gates of the body, then it may be known that Harmony is increasing. Greed, outgoing energy, undertaking of actions, restlessness, desire—these are born of the increase of Motion, O best of the Bhâratas.
