Acharya Prashant explains that there are not two separate worlds, material and spiritual, but only one world. Worldliness is staying on the surface of this world, while spirituality is diving deep into it. He uses the metaphor of a riverbank to describe three types of people: the worldly, the criminals, and the spiritual. The worldly are the majority (990 out of 1000) who sit on the edge, afraid to dive deep due to fear of the unknown. The criminals (9 out of 1000) are those who dive without awareness or preparation and end up destroyed. The spiritual person (1 out of 1000) is the trained diver who enters the depths of nature with full consciousness and awareness, eventually liberating themselves and others.
