Preface

Energy is delight. There is no other delight. The very vitality,the very energy of being,is delight,is bliss.- William Blake, English Poet.

Electricity can be dangerous. My nephew tried to stick a penny into a plug. Whoever said a penny doesn't go far didn't see him shoot across that floor. I told him he was grounded. Tim Allen

Consciousness give rise to thoughts as electricity gives rise to light -Dwaraknath Reddy

I am not a doctor, but, still I understand the importance of heartbeats, blood pressure and body temperature. I know what they are and what should be the respective and normal standards of these vital human factors.

The Doctor of medicine may understand about the energy flowing and causing the heart beats – but, every one of us may not understand or have the same level of understanding about the electrical energy that flows in to our households.

Eightu,

I remember my two year old baby crying for light to be switched on, the moment he wakes in the middle of the night. The light should be switched on.

There should be electricity flow in to the hidden wires that connect the bulb to the source
