Brief and simplified discernment to further inspire and complement the following exploration https://arxiv.org/pdf/2110.00580.pdf. And all related scientific and epistemic-ontic explorations and quests. And as had discerned in diverse ways in diverse past discernments:
Even there is only One World as All That Exist and Ever Exist, there are many interdependent and interconnected or intertwined and entangled realms and worlds as fractal sum of parts of the greater whole. And which can be defined and specified as:
1.0 Known biologic world. And which has many realms such as diversity of mountains, lands, forests, ocean, rivers, underground, and biodiversity. And as well as the many observable and unobservable diversity of macro and micro realms.
2.0 Currently unobservable immaterial biologic world. And which has infinite realms which are isolated-coupled-entangled from each others. And the main differences (and among many others) between known physical world and immaterial world respectively are:
2.1 Known biological world are of macro, micro, quantum, and beyond forms. And is essential or existence is to create immaterial life and existence in the immaterial world. Another way of saying is known physical world is of many composite body-mind system world. And can be illustrated through empirical science of body elements, parts, and entire body are replaced throughout life cycle. Another simple way of saying is whether one experienced and or believed or not, one body elements, parts, and entire body are replaced or reformed throughout life cycle. And which clearly indicated active natural process and mechanism.
Furthermore, if conscious and aware, then entangled past-future-present states of mind would be more obvious. And which correlated with empirical of NDE experiencer which usually are expressed as past-present-future as one or there is no time. A simple way of saying is a causality or facilitated from meanings or by unified omni-sentient, omni-present, and omni-potent phenomena or process and mechanism.
2.2 Known many composite body-mind system world, despite having many realms, cannot be naturally isolated-coupled-entangled from each others since it is composed of macro or existing as local and non-local (i.e. non-local made possible by subtle body or body-mind) world.
3.0 Immaterial biologic or existential realms are based on quantum and beyond spectra-field. And therefore, is non-local (i.e. transcending all realms and worlds made possible through subtle body (for non biologic or non sentient) and subtle body-mind (for sentient, in particularly evolved sentient such as human species). And therefore, realms can easily be isolated-coupled-entangled from each other. However, there are still intertwined and entangled as parts of sum of parts of the greater whole. And the fractal evidence and empirical data are well illustrated in quantum computer and information where about quanta and non-organic elements can be isolated-coupled-entangled from and with each others.
There are many reasons such as:
All That Exist and Ever Exist are through self-realized and self-actualized process and mechanism of being and becoming as fractal parts of sum of parts of wholeness. And becoming more and more perfect or more and more omni-sentient, omni-present, and omni-potent. And as such:
The most relatable and becoming more and more obvious to the human conditions and experience (in particularly from mystical and transcendence experience) over millenniums upon millenniums are: essential for the dynamic and transformative universal process of being and becoming of infinite potentialities of possibilities in the known physical world. And beyond.
And the most conscious-aware sentient that resonate the most with the "Ground of Being" would be the closest to the "Ground of Being". Another way of saying, the better and better sentient characteristics and qualities (i.e. higher and higher consciousness and awareness as well as sentient characteristics and qualities. And therefore, better and better form-formless), the higher and higher sentient realms. And closer and closer to the "Ground of Being" whether in the known physical or beyond (certainly would be after known physical life transition). Another way of saying is one (individual. And also collective) consciousness-awareness and sentient characteristics and qualities (and therefore, form-formless) would define one own realm since universal process of being and becoming are inclusive, common, and applicable to all. And of free will (complemented, supported, and facilitated by the greater whole in diverse ways) as expressed by now better recorded, interpolated, extrapolated, and correlated empirical of the human conditions and experience of individual and shared OBE-NDE globally. And which basically, can be illustrated through simple process and mechanism of topology structure function order of intertwinement and entanglement of form-formless as in applied spectra-field such as quantum topology, computation, and information.
And of course, immaterial realms and world are the only way eternity could be achieved or possible.
And what just mentioned (among many other reasons), also indicated that space-time-information are irreducible and emerging or through dynamic and transformative universal process and mechanism of intertwinement and entanglement or universal process of being and becoming. Otherwise, sentient experience, consciousness and awareness, and form-formless would never be possible. And as demonstrated through many evidence and empirical data of such as common biologic descendent or evolution, past-present-future states of mind, entanglement and emergence phenomena, and among others or more specifically, of infinite potentialities of possibilities. And which manifested in diverse ways. However, they all are based on universal process of being and becoming basing on fractal "Dependent and Interdependent Origination" and "Dependent and Interdependent" (i.e. nothing has its own inherent intrinsic independent existence) as sum of parts of the greater whole. And are being revealed through applied sciences and engineering. And in complementary to better recorded, extrapolated, interpolated, and correlated sentient or human conditions, experience, and potentials.
