Hi Peace of mind, I guess the cables and cords could be an obstacle yes.
For ascension, like Jesus did on a cloud to the Heavens, I mean.
Just kidding
My second guess is that our consciousness is capable of transforming all kind of unbalanced or harmful frequencies that radiate from devices and electricity sources. That's part of the ascension process and not a hindrance, I believe
we have to learn to trust that manifestation power. There's so much roads that lead to Rome and from Rome. Here are some links on cell phone blessing and one leading to a topic on ascension, by Chris Bourne.
