Who says the master has to exist on the physical plane as we know it? If you are trying to pull in energy, focus on the universal energy that surrounds all of us. Tap into "the force". A good visualization for this is to imagine you drawing the energy from the sun or a large pool of limitless energy. There's way more universal energy to access than using our own or another persons.
Give it a go and let me know how that feels.
Peace,
Peter
