Therefore, be "unattached"; let things work; let brain centres work; work incessantly, but let not a ripple conquer the mind. Work as if you were a stranger in this land, a sojourner; work incessantly, but do not bind yourselves; bondage is terrible. This world is not our habitation, it is only one of the many stages through which we are passing. Remember that great saying of the Sânkhya, "The whole of nature is for the soul, not the soul for nature."
