Not sure what you mean by "this" but my ideas come from the bible, One such reference is in Luke where Jesus tells them the kingdom is within [depending on the translation] You should also be aware that the kingdom of God is not a physical place it is a state, those who are subject to God are part of his kingdom but many do not see the kingdom even though they too are a part of it.
[KJV] Luk 17:21 Neither shall they say, Lo here! or, lo there! for, behold, the kingdom of God is within you.
[ISV]Luk 17:21 People won't say, 'Look! Here it is!' or "There it is!' For the kingdom of God is among you."
[ALT]Luk 17:21 neither will they say, 'Look here!' or 'Look there!' For listen! The kingdom of God is within [or, among] you*."

Gospel of Thomas
3. Jesus said, "If your leaders say to you, 'Look, the (Father's) kingdom is in the sky,' then the birds of the sky will precede you. If they say to you, 'It is in the sea,' then the fish will precede you. Rather, the (Father's) kingdom is within you and it is outside you.
