A practitioner asks: “It was discussed earlier how invoking our higher selves specifically creates personal advantage to some degree above and beyond making requests directly to Creator. In a similar way, would invoking the help of our vastly powerful oversouls be similarly advantageous by virtue of additional personalized focus on our 400+ incarnations?”

This is not a practical strategy to implement. The body of the soul itself is vast but is not assignable to be a source of influence or support to you as a physical extension. That is what the higher self is there for, to be the intermediary, in knowing how to call forth more energy on your behalf as well as healing maneuvers that can help you come back into better alignment and overcome adversity, so the higher self is the highest local level of appeal available to you.
