In our Physics class, we had a whole chapter dedicated to achieving perpetual machine. It is that dream thing that doesn't exist!
Basically, this is how the theory goes. You work on a machine and machine does something for you in return. Like a bike. You rotate the paddle and bike moves forward. Its this effort of yours that makes the machine work for you. Good enough. We should be happy about it. But are we? Ever?
We learnt that the machine always gives back lesser than we gave it. That's not right. We are humans, for crying out loud. We are never happy with what we have.
We want more. To get more is the aim. Wait, that's not it. The real aim is, to get everything without having to give. No, really.
And that's leads to our fantasy of a perpetual machine. A machine that keeps giving once you hit start button, without asking anything in return.
Pause. (A long one).
We humans want everything to be a perpetual machine. I think we need to take a moment to think about this arrogant attitude. "We oughtta have it 'cuz we deserve it!" won't help. It pops up everywhere. Respect, dedication, love, passion, compassion, and all of those intangible feelings that actually make things worthwhile cannot be imposed or asked back in return.
You just have to give. With an open heart. If not for yourself, for others. Just like that. Life is not a perpetual machine, its more than that, but you have to make the first move.
