Demons think that they will manufacture their own process of yajna and prepare some machine by which they will be able to reach any higher planet. The best example of such a demoniac man was Ravana
Bhagavad-gita As It Is
BG Chapters 13 - 18
Each demoniac person thinks that he can live at the sacrifice of all others. Generally, a demoniac person thinks of himself as the Supreme God, and a demoniac preacher tells his followers: "Why are you seeking God elsewhere? You are all yourselves God! Whatever you like, you can do. Don't believe in God. Throw away God. God is dead." These are the demoniac's preachings.
Although the demoniac person sees others equally rich and influential, or even more so, he thinks that no one is richer than he and that no one is more influential than he. As far as promotion to the higher planetary system is concerned, he does not believe in performing yajñas, or sacrifices. Demons think that they will manufacture their own process of yajña and prepare some machine by which they will be able to reach any higher planet. The best example of such a demoniac man was Rāvaṇa. He offered a program to the people by which he would prepare a staircase so that anyone could reach the heavenly planets without performing sacrifices, such as are prescribed in the Vedas. Similarly, in the present age such demoniac men are striving to reach the higher planetary systems by mechanical arrangements. These are examples of bewilderment. The result is that, without their knowledge, they are gliding toward hell. Here the Sanskrit word moha-jāla is very significant. Jāla means "net"; like fish caught in a net, they have no way to come out.
