So the consciousness is there in the trees also. But that has been known by the scientific apparatus, but according to our Vedic injunction, that is already mentioned in the śāstras, that the trees have consciousness. They are also living entities. Don't say that they are without life. They have got life. And therefore the system is... Just like we pick up flowers from the trees for offering to Kṛṣṇa, but the injunction is that after evening you should not touch the tree. The idea is that they are sleeping, don't disturb. So the consciousness of the trees are admitted in the Vedic literature. Similarly, the consciousness is developed from tree to worms, microbes, worms, germs—their consciousness is little more higher. Then birds, their consciousness is little more higher; then beasts, their consciousness is little more higher. This is development, gradual process of evolution. Gradual process of evolution means gradual process of developing the status, the state of consciousness. In this way the consciousness in human form of body is further developed, very nicely developed. And similarly, there are other elevated living condition in higher planets. They are called demigods. They are far advanced, very more and more intelligent. Their standard of living, their everything, is far, far above than all these planets, thousands and thousands of times. Just like we can discriminate here, even on this planet. Your standard of living, from materialistic point of view... Just like to get a motorcar in this country is ordinary thing, but in our country, in India, if somebody has got a motorcar, he's considered to be very rich man. Here even a worker goes on motorcar, but in India only a person who is very rich, he can have a motorcar. As there is difference of standard of living from one country to another, similarly, there is difference of standard of living, standard of duration of life, standard of intelligence, standard of developed consciousness, everything different.
That is stated in the Brahma-saṁhitā: yasya prabhā prabhavato jagad-aṇḍa-koṭi-koṭiṣv aśeṣa-vasudhādi-vibhuti-bhinnam (Bs. 5.40). If you try to read Vedic literature... Not very many. Try to understand Bhagavad-gītā as it is. Try to understand Śrīmad-Bhāgavatam. These two books will give you sufficient knowledge, and we should take advantage of it, because our consciousness is developed. We should not waste our time simply reading these all nonsense literatures, sex literatures. Simply wasting their time. Tad vayasaṁ tīrtham. To read nonsense ordinary literature and books or newspaper is compared just like the pleasure place of the crows. The crows, they are very much attached to the rejected refuse, garbage. In your country I don't see many crows, but in our country there are many crows, and the garbage section is pleasure, pleasuring place there. Where rejected things, they take pleasure in that. But the swans, the ducks, they take pleasure in clear lake with lily flower, nice garden, and nice birds are chirping. They take pleasure in that place. Similarly, there are classes of men also like crows and like swans. The swans, they will take pleasure in this kind of literature, Vedic literature. And the crowlike men, they will hunt after that rejected garbagelike things. Punaḥ punaś carvita-carvaṇānām (SB 7.5.30). What is there in the sex literature? There is no new information; the same sex life, that's all. Sometimes half-naked, sometimes naked, sometimes this, sometimes that, but the central place is sex.
