Is Spiritual Cultivation to Empty the Realm or to Empty the Self?

What dharmas are encompassed within the realm? The realm is dust. Dust refers to all forms, sounds, scents, tastes, tangible objects, and mental phenomena that stand in opposition to my conscious mind. This includes all dharmas pertaining to human affairs and physical principles, including the five aggregates of both self and others. When the sense faculties and their objects come into contact, consciousness arises. Where there is consciousness, there is discrimination, leading to the stirring of thoughts and mental activity. So, in cultivation, is it the realm that is to be emptied, or is it the self? It is the self that must be emptied first. When the self is emptied, the realm becomes empty. It is not that the realm becomes empty first and then the self follows.
If the realm is non-existent, then I am non-existent. If the realm exists, then I exist. What kind of practice is this called? If this is also considered practice, then when non-Buddhists cultivate and attain the four meditative absorptions and eight concentrations, voiding the phenomenal world, yet retaining the self, have they severed the view of self? Who is emptier than the non-Buddhists? Those who cultivate the realm are originally those who follow the realm and are turned by it. Those who are turned by the realm are ordinary beings. If the self is emptied, is there still dust? The dust follows and becomes empty. If you are not empty, all realms arise. If your mind is empty, all realms transform into nothingness.
