This brief discernment is to complement the following analysis https://futureandcosmos.blogspot.com/2019/06/so-many-better-arguments-against.html:
To create, nurture, transform, and purify the subtle body or emerging spirit-soul potentialities of possibilities, the physical body is essential. In simple words, without the physical body as mean for the subtle body creation and development or perception and experience of the world, emerging spirit-soul would not be possible or there cannot be spirit-soul without physical body through nature evolution and optimization process of being and becoming. And all these are within the whole universal process and mechanism. In other words, the many sentient composite body-mind system process of being and becoming is part of the greater whole process dynamic and interactive process of being and becoming. And therefore, both the physical and subtle body-mind are parts of the process. And which is why at physical death, the emerging spirit-soul could transition to new potential realms and worlds while the physical body is returned to nature in the known physical world. And which is why there are memories and information that pertain to the physical body. And memory and information that pertain to the subtle body-mind as had suggested in diverse ways in past discernments.
Furthermore, since subtle body-mind is achieved through process of being and becoming, spirit-soul potentialities of possibilities are only in evolved species such as human (i.e. there are thresholds). This should now be more obvious through the sciences of such as resonance, topology, and entanglement (such as relativity, symmetry, phase transition, symmetry breaking, intertwinement and entanglement, topology protection, and emergence).
An extremely simple analogy is a wireless device has software (i.e. OS, software, applications) and hardware that allows it to interface to network(s). And ultimately to a system (and the system has total operations and control of the device) And vice versa. However, the wireless device has no subtle device within it nor can create one while the many sentient composite body-mind system does through the intertwinement and entanglement with and in the local and non-local cosmos. And as mentioned, while the system has total operations and control over the wireless device (total deterministic even if it is AI since adaptation in technological evolution content and context is not the same as process of being and becoming), species has free will for meaningful transformation and evolution through the process of being and becoming with the greater whole (i.e. the whole process and mechanism is deterministic while the potential of being and becoming is non-deterministic since one has or was given the free will).
Materialism, physicalism, idealism, and related philosophies or concepts do not only plague present thinking and paradigm but rather, they were also very much popular or the norm in early days of naturalness-spiritual (not referring to religion) development and practices that span millenniums (since after all, naturalness-spiritual practice just as science, is also a process of trials and errors of perception and experience of being and becoming. And inquiring about nature, life, and existence epistemology and ontology through both shared (body-mind) and different or alternative means with naturalness-spiritual relying more on the experience (inner senses and subtle mind) while science more on the perception (i.e. physical senses cognition and intellect).
And therefore, their fusion or make use of both would greatly strengthen and complement the whole or many sentient composite body-mind system. In other words, the whole would be far greater than sum of its parts). And even now since all traditions basically remained the same or worse due to either no longer practice, lost of knowledge, neglect, remain static, conformance, and forbidden practices. In addition, many traditions were diluted due to integration with such as indigenous knowledge, imperial conditions and demands, make them practical for diverse communities and societies, and among others (what mentioned here are recorded in many ways in history. And even are still very much present day norms which are why words for spiritual and religious markets are popular. And can be easily studied and known). In other words, there are problems in both science and naturalness-spiritual. And thus, it is meaningful and purposeful to converge and integrate to complement and strengthen each other. And advance the common and greater good for the betterment of all. Therefore, it is essential to protect, nurture, develop, and better the many sentient composite body-mind system for present and future generations as well as the species not only in the known physical world. But also far beyond.
Therefore, it would be wise to heed or adapt meaningful wisdom and transformative practices for the scientific quest toward realizing and achieving essential nature of reality and truth. And therefore, actualizing essential ways of life and best practices. And rise to the opportunities and challenges of solving out of this world complexities. All the while advance meaningful and essential life and social essentials, needs, values, and common and greater good as well as prevent and eliminate harm, injustice, and suffering for present and future generations, humanity, species, and sentient.
In addition, naturalness-spiritual is about the real and true self. And therefore, are inherent rights of nature and essences of being as much as all known established human rights-dignity and beyond as well as well being for not only the individual but also the collective and greater whole. Therefore, are meaningful and purposeful priorities, investments, collaborations, and efforts as well as great opportunities for all to advance the common and greater good. And a great transition toward greatness.
