This is just me. But I have always liked to think that you link a power source to the Grid itself to create Power Rangers. This is why the Animarium Worriers and Mystic Worriers of the past weren't Power Rangers. Their powers were later connected to the morphing grid so their heirs couls be Power Rangers. The Ancient Samurai obviously connected to the grid during their lifetimes. So I would say the grid and power source goes hand in hand. But thats just how I like to think of it.
