Panchadashi 1.30

For enjoying joy etc., these souls perform actions, and for performing actions later, they consume enjoyments. In this manner, these souls are like those insects in a river that come out of one whirlpool and get trapped in another. Similarly, these souls go from one birth to another. They never get any rest or joy.

Because these souls do not have accurate knowledge of the self essence, they perform actions (appropriate to the bodies they have acquired) in order to experience happiness. Then for performing those actions, they keep consuming the requisite enjoyments. Consumption of results becomes essential because, if after performance of actions, the souls do not gain results of actions, then those beings will not have desires spring up in them, and then they would not have to take effort for those desires.

So when a being consumes an enjoyment, he then dives into those actions with hundred times more enthusiasm, and when he finishes those actions, he waits for their results with thousand times more anticipation. So this cycle of action and enjoyment never ends.

The state of such souls is like insects that flow in a river, that go from one whirlpool to another, and never rest. Similarly these beings are trapped in action and enjoyment, and attain one birth to another. These misfortunate ones do not even get a glimmer of sustainable happiness.
