PURPORT

Here is an attempt to find the supreme controller, or isvara. Everyone may be accepted as an isvara, or controller, but still such controllers are controlled by others. For example, one may have undergone severe austerities but still be under the control of anger. By a scrutinizing analysis, we find that everyone is controlled by something else. No one, therefore, can be the true controller but the Supreme Personality of Godhead, Krsna. This is supported by the sastras. Isvarah paramah krsnah: the supreme controller is Krsna. Krsna is never controlled by anyone, for He is the controller of everyone (sarva-karana-karanam).
