At least we know that energy can't be destroyed; and that we are made of energy... For me there's no doubt about it!
I've discovered that meditation is not a religion, in fact it is just a way of connecting with your inner-self. So it works even for atheists! I believe that this is the only way to discover the true about ourselves. If we have been living for so many years in different bodies, learning and doing the same things over and over and over... I believe it's time to break the cycle understanding that We Are Not Our Minds, we are someone or something else behind them. What is it? I definitely want to learn more about this mystery; and I invite you to do the same if you want to be free of your own desires and suffering.
First step, observe yourself everyday and each time you can. You can have the power of conciousness if you like; but you have to train hard. It's not going to be easy but I think it is going to be worth it.
Good luck traveller!
