How much do we have to do from our end, as practitioners, and how much can we use powerful cogent requests for Creator to be the detective in finding the most important and significant issues and lifetimes to heal in our DSC-TR sessions?

In effect, you have total power and authority to decide which approach you would like to follow, so you could, in the absence of very specific definitions of multiple client issues that are well-chosen and appropriate and make sense to you with all you know about healing and people's dilemmas, use your psychic ability to explore the akashic records with the intention to see for yourself what the client has been through that is germane to a symptom or issue they might struggle with or, in the absence of much knowledge about the client's situation, set the intention to see key events causing current lack of progress or even general unhappiness, and so on, and then target the healing work to what is observed personally. Alternatively, requests could be made to Creator to apply our greater insight to help you in creating a prioritization of what is highest and best to be addressed, as you will be exploring further.
