Energy (n.) clings to its object and, when transformed, carries something of its previous character into the next form — so fire-boring looks like a sexual act and is not one any longer.
Energy (n.) is admittedly a mere verbal concept — yet so extraordinarily real that your Electricity Company pays dividends out of it.
Energy (n.) implies polarity: a current needs two different states to flow between, so every libido symbol either is a pair of opposites or breaks down into one.

Energy (n.) being God or God being energy concerns the practising psychologist very little — how could he know such things? What he must be able to do is give appropriate explanations.
