What a holistic approach entails
I am not going to talk about esoteric levels here, just practical levels that emerge within a valid evolutionary journey. Firsly we have the animal body. To play its part in optimal health it requires a diet that is going to supply it with all vital nutrients, beneficial gut microbes and not much in the way of devitislised, junk or chemically laden foods. It requires exercise, fresh air, sound sleep and a natural environment. Within the basic naturopathic laws for the physical-animal body, it responds to enhanced nutrition, enhanced waste elimination and natural substances such as herbs. The nutritionist, naturopath or physical body worker commonly focus on this level of the animal body. However, it is also the animal body and particularly the most primitive part of the body-mind that registers survival traumas. Some psychologically based therapies address this and attempt to accept and relive, or otherwise drain out the affects of, these traumas.
Working with the levels of being
Then we have the more human, adult nature and it's adult human emotions and desires, beliefs, social, medical and religious conditioning and so on. Social conditioning and a society's laws are always banning someone from being overly animalisitic in certain ways, or believing something too radical, whilst other equally absurd ways are entirely permitted. Many modalities of psychotherapy will address these problems, the problems of the suppression of the animal's nature with it's basic desires for food, reproduction, mating, territory, or pack hierarchy, but many are unable to access the survival level, the traumatised lower animal and unable to support the physical body's healing forces with naturopathic principles.
So far, none of this requires us to be anything other than an animal body in a human society with human problems. None of it requires us to have a deep inner connection to a more encompassing consciousness, although some of the psychotherapies come to assume a framework of something numinous - unseen forces at play creating connections with the world and pushing us into playing specific roles.
So next we have the level of the collective unconscious. We can play with this level, the level of myth and archetypes in some disciplines in a fantastically opening way. My experience in pointholding is that when someone connects to an archetype rather than personal memory (since it is something beyong personal memory) the experience evokes powerful emotional energies which surge through the being on the utterance of relevant word-pattern phrases. The further from collectively acceptable such archetypes are, the more powerful are the energies experienced. Such an experience may have little or no correspondence to life circumstances, although, to be able to contact such an archetypal energy means that it has always been lurking within, presenting itself as a shadow behind certain experiences.
Overlapping with and encompassing all the previous levels is that we would think of as the spiritual. I doubt we can "work with" this level of experience as it is something beyond our little ego's capability to do so. We might be able to learn with our minds about this level, but realisation of deep inner principles and our place and purpose in the world can only be unveiled from a process not in the most part ego guided. When a discipline works from this level, it encompasses all the other levels, it will be pushing to remove blocks from each of those levels in a sequence of importance which is not possible to grasp outwardly. We might relive our birth, we might go into childhood memory, we might shed a whole load of social conditioning, we might touch into previous lives, but then again our personal process from this angle will not be focused on such things. They come up to be resolved as needed in the greater scheme of things. What is important from this level? That we grasp HOW to transmute. That we perceive and transmute the serious errors in our past behaviour which are imprinted somewhere on our being. And what is meant by that? Not that we wandered haplessly yet again into being the victim, but how we have seriously harmed or paid no heed to harming other beings with a living soul through abuse of power. It becomes plain that such things buried deep within us are the most important and how a spiritually valid process has always been heading for these things by peeling off layer after layer of more superficial things.
Working in all channels of awareness
I appreciate the work of Process Oriented Psychology and gained something from understanding their concepts of channels of awareness. We have our internal channels of awareness as sensation; emotion; desire and movement. Sensation can be broken into our 5 senses (as taught in school) as well as balance and the "where I am in spacially " and what are called interoceptive sensations from body parts - such as hunger and full bladder. Then we have our relationship channel where we have projection and "dreaming up" in our individual relationships with others. The widest channel is the world channel where we are identified with particular world problems. Resistance, as polarisation, or unconscious content, manifests in any or all such channels of awareness.
If we work primarily with disciplines that do not include certain channels, we are going to be limiting ourselves in a far from optimal process, plateauing in our gains in consciousness when we bang up against the limits of our most unconscious channel. If we have a large amount of unconscious content in one channel, we have probably felt vulnerable when in it and been drawn to therapy modalities which don't include it. Most obvious to me is the clunky, uncoordinated meditation devotee who would gain so much from doing an expressive dance or drama therapy. It's opposite is also true, the extravert who is drawn to expressive therapies and therapies which include role playing with relationship conflicts, so obviously would gain from long still meditation such as Vipassana that ban all forms of extraversion, or from body electronics which requires a still containment of intense inner energies.
Peter is a practitioner and teacher of body electronics and well read in the works of Carl Jung and some of his followers. As a natural researcher he is always looking for greater understanding of the principles and details of this great inner work.
