This seems to fit very well with the Biblical teaching which states that the physical world is always in the process of "passing away" while the spiritual world is always "present" and "eternal" and indeed, it is the root souce of all Reality (which is grounded in God, of course):
KJV Hebrews 11:3 Through faith we understand that the worlds were framed by the word of God, so that things which are seen were not made of things which do appear.The "things which do appear" refers to the visible physical world and the "Word of God" is the source of this visible reality that is itself not seen. The more I look, the more I see this teaching throughout Scripture:
Matthew 6:19-21 19 ¶ Lay not up for yourselves treasures upon earth, where moth and rust doth corrupt, and where thieves break through and steal: 20 But lay up for yourselves treasures in heaven, where neither moth nor rust doth corrupt, and where thieves do not break through nor steal: 21 For where your treasure is, there will your heart be also. "Heaven" is a place of "incorruption" and by implication, "permanence" and "eternality" whereas the "earth" is visible and corruptible and impermanent. This then coheres with Paul's teaching on the nature of the resurrected body:
1 Corinthians 15:42-49 So also is the resurrection of the dead. It is sown in corruption; it is raised in incorruption: 43 It is sown in dishonour; it is raised in glory: it is sown in weakness; it is raised in power: 44 It is sown a natural body; it is raised a spiritual body. There is a natural body, and there is a spiritual body. 45 And so it is written, The first man Adam was made a living soul; the last Adam was made a quickening spirit. 46 Howbeit that was not first which is spiritual, but that which is natural; and afterward that which is spiritual. 47 The first man is of the earth, earthy: the second man is the Lord from heaven. 48 As is the earthy, such are they also that are earthy: and as is the heavenly, such are they also that are heavenly. 49 And as we have borne the image of the earthy, we shall also bear the image of the heavenly. It appears that "heaven" describes a relationship with God, that is, Ultimate Reality.
Thank you for introducing this very interesting topic.
