A: Death is just passing through a door that is not accessible to the living except on the mental planes. If his father wishes to fully honor his son and his choice, he might do well to use this event as motivation to develop himself in a more fully spiritual way. More than that, he could help others in lieu of his son for his son.
There is so much (deliberate?) obfuscation around the topic of death, which creates so much fear, grief and sadness (all emotions that feed 4D STS from what I've read of Laura's work). As I mentioned in a post above
Reflecting on the whole Spirit Release Therapy and attachments from the Knowledge and Being videos by Laura, it would seem that indeed Western society and monotheistic religions have made us very fearful of the process of dying. Hence the attachments (they don't know how to transition to 5th D). The very institutions that are supposed to be a source of spiritual guidance through life and into death, have failed humanity miserably.
It would be so healing to the grieving process and the transitioning if we know what to expect and how to safely go to 5D when it's our time. If we had knowledge that death is transition, that the body is just a vehicle or an outfit that one needs to change every so often to learn, grow etc and that it is the Soul is what matters, things would be so different.
