Is it appropriate to request training for the deep subconscious and cellular consciousness in how to call on the guides, guardians, higher self and Creator for protection, or should they only call on higher self and Creator?

While you are concerned that an individual might settle for help from a spirit guide and not consult higher self or Creator, you are under-appreciating the help available, when you request training from on high in how best to consult the various members of a spirit team. We would not leave to chance who the client might choose, to play favorites in focusing only on one level of the divine realm, and thus limit options as to the scope of a reply to that individual level alone. When you include all potential sources of assistance in a request to have training to engage in an outreach by a particular level of the mind, so that the client's inner self will have greater resources at its disposal, we will take pains to educate that level of the mind, who is out there that can be trusted, and then not only how but when and for what kinds of issues it is best to address any particular level. So you can leave those details up to us and not be concerned about setting up a limitation inadvertently.
