In this material nature, or material world, we have got three kinds of sufferings, tri-tāpa-yantana. Śrī Sanātana Gosvāmī inquired, "Why these three kinds of miseries inflict pains upon me?" Ke āmi kene āmāya jāre tāpa-traya. Tāpa-traya. Tāpa means painful condition, tāpa. Just like if you touch fire, it creates a painful condition by burning the part, similarly, this world is also a blazing fire, saṁsāra-dāvānala. The rascals, they do not know. They are always out of the three kinds of miserable condition. Everyone is in some way or other under these conditions. These conditions means it is... These kleśāḥ, painful conditions, they are created by three causes. What are those causes? Daiva-bhūtātma-hetavaḥ. Daiva means created by the demigods. Daiva. Devatā. Just like this rain department, water department, is under the control of Indra. So Indra can supply water just to your requirement, or sometimes he does not supply, or sometimes he supplies over, over requirement. Ativṛṣṭi, anāvṛṣṭi. Anāvṛṣṭi means no rain, and ativṛṣṭi means excessive. So we don't want excessive or less. We want just proper. So this is under the control of the devatā. You cannot say... You may be very great scientist. You cannot say that "It is under my control." When there is no rainfall, you cannot say, "All right, we are scientists. We are creating rain." You can theoretically say, "Now we are making progress. In future."
