They say that, "So far these necessities of life are concerned, they are ready, supplied." In any life, either in human life or in birds and beasts, lower animal, trees, plants, that is ready. Therefore we should not waste our time for these things, but we should be ready to enquire about the Absolute Truth.
So human intelligence is there to enquire about the Absolute Truth. So they have got better developed consciousness or intelligence than the lower animals. So that higher intelligence should be utilized for enquiring about the Absolute Truth. So that is. . . Vedānta-sūtra says, janmādy asya yataḥ (SB 1.1.1), athāto brahma jijñāsā. This life, human life, is not meant for wasting time for adjusting how to get better food, better shelter, better sex and better defense. So the human intelligence is that, when one thinks, that "If these necessities of body are ready even for the animals and beasts and birds, then why not it is ready for me?" It is ready for the human being also. That is a fact. We see when human beings are uncivilized, the ready food is there. They live in the jungle—there is fruit ready for eating. Everything is ready there. They do not know how to produce food, the uncivilized man. They eat some animal. They eat some fruit. This is already ready.
