This principle states what you put out comes back. But it's beyond that, because its not just what you put out financially
(and for most atheists this what they care with most, there material wealth since there's nothing greater in the world and nothing after anyway) this means that giving all your heart to your family, community and going out of your way even to your own detriment to help others should come back to you. Now if it comes back as some form of Karma that means there's a external world you can't see opperating behind the sceans right? So if your an atheist and you believe in karma and then your not a true Athiest at all, No, your Agnostic! And since your agnostic why be critical of those who have gone further and actually encountered that being/beings who do call the shots and have learnt more, if you don't seek to understand what that invisible force is then your not just Agnostic but your also now choosing to be Ignorant (and you might take that as insult but its not ment to be, it's just saying you are choosing to IGNORE or be ignorant of that force rather than try understand it )
A true Athiest doesn't believe in Ghost,Karma, or any such invisible force...those who do are Ignorant Agnostics, and that level of ignorance depends on how much spiritual growth you have obtained.
I can assure you there is a God!( Check over the other thread occasionally about Spirit world,World works)... We're still yet to get to some of the deep topics like Indemnity. How fasting and other practices allow for payment. But what is the most powerful force in the world including in the NonCopereal world? It's love! What I'm telling you is if you give pure love to everybody then you won't need to seek God or Spiritual things, they will seek YOU! And not matter how hard you try not believe they will want to be around you and introduce themselves to you. Love is the answer atheists , try believing and trust in something more important than you. Take my test, what have you got to loose? If there's nothing out there as you think....TAKE THE TEST! Once you encounter something and become Agnostic , keep going and learning or else you are just deciding to continue to stay ignorant. Ask God to teach you and guide you with his Eyes.
I see no evidence of ghosts, religious or any other kind. The "evidence" presented on those ghost-hunter shows demonstrates quite well that magnetic and electronic phenomena are not thoroughly understood, but in no way presents evidence of spirits - unless they are defining "ghost" as a magnetic anomaly.
I had a personal experience that some people would call a "ghost." According to Ute legend, a white hunter back in the 1830s or 40s killed a mountain lion in what is now Wildcat Canyon just west of Durango, Colorado. Ever since, the mountain lion's ghost has haunted Wildcat Canyon. It is friendly to Indians, but hates whites. One dark, rainy night I took my pickup into town. As I passed the mouth of Wildcat Canyon, I saw something large - larger than my pickup - and blacker than the night in the middle of the road. It scared me half to death. I was past it almost before I realized it was there. I have no idea what it was, but an Indian friend told me I had seen the wildcat's ghost. There was obviously something there that I cannot explain, but lack of an explanation does not constitute evidence.
