Threefold miseries—This is another feature of the influence of the three modes of material nature. All living entities within this material world are controlled by material nature (prakṛti), who subjects them to threefold miseries: adhidaivika-kleśa (sufferings caused by the demigods, such as droughts, earthquakes and storms), ādhibhautika-kleśa (sufferings caused by other living entities like insects or enemies), and adhyātmika-kleśa (sufferings caused by one's own body and mind, such as mental and physical infirmities). Daiva-bhūtātma-hetavaḥ: the conditioned souls, subjected to these three miseries by the control of the external energy, suffer various difficulties. This suffering is the impetus for seeking answers to the fundemental questions of life: Who am I? Why am I suffering? How can I get free of suffering? See Modes of nature, Prakṛti.
