I think your dad and his condition are sincerely cared for by many people on this forum 
nevertheless, sincere wishes must be carried out very quickly
This is the most important aspect of manifestation - faith, or the power that drives our heart’s desires
this is why prayer is so powerful - because it comes from the heart, and it is the heart that is the initiating pathway
the emotion emanating from the heart is the most important thing, it is what is the vortex. Harmonizing our mental gaze with our feelings is the fireball for change
Although, personal manifestation should bring personal change and experience, the chain that is created has a positive impact on those around us
Everything will be fine @Hauru
don’t forget the medical fields
