Because you are feeling heat, extraordinary. Therefore you invented this fan. Or mosquito curtain. Just struggle. This is called adhibhautika.
Then adhidaivika. If there is no rain, there will be no food production, and the rice will go eight rupees per kilo. And you have to suffer. Durbhikṣa. Even people are not willing to give you bhikṣā. "Because the rice is so costly, how can I give?" That is called durbhikṣa. Durbhikṣa means when you do not get even bhikṣā. This is the most lowest profession. It is highest also. The sannyāsīs, they go door to door, bhikṣā. Brahmacārī go to door to door. Our Vedic civilization is that in the society there are four divisions: the brahmacārī, the gṛhastha, the vānaprastha and the sannyāsī. Suppose there are hundred men in a village or in a place—the society is divided into four āśramas: brahmacārī, gṛhastha, vānaprastha . . . so . . . this is material calculation. Suppose if there are hundred men, seventy-five men are to be considered brahmacārī, vānaprastha and sannyāsī. So these seventy-five men will live at the cost of the twenty-five men, gṛhastha. Gṛhastha has to give alms to the brahmacārī, to the vānaprastha and to the sannyāsa. Just see how nice communism. The one twenty-five-percent group, they are earning, and they are maintaining seventy-five men. So they are living by bhikṣā. Brahmacārī will go door to door, "Mother, give me alms," and they'll give. The sannyāsī will go. So when this bhikṣā will not be available, that is called durbhikṣa, famine. This is adhibhautika, adhibhautika . . . er, adhidaivika. You have no control.
