Explanation:

By ignorance one thinks that he has left everything by not imagining anything in the world. In such state also, the person is thinking about the empty space, which is the first item of the creation. Hence, it is not possible to think crossing the entire creation as long as the awareness exists. In the meditation, one claims that he is concentrated on the self, by leaving every aspect of the world. But on analysis, you will find that in such state of meditation also, your awareness did not cross the creation, since your blank mind means that it is thinking about the vacuum, which is the space or primordial energy that is the first item of creation. You are thinking that your mind has gone beyond the creation but actually it is not so. The reason is that your mind can never go beyond the spatial dimensions and touch the unimaginable God, who is beyond space.
