I'm not religious but I'd definitely say that I am without a doubt a spiritual being. Maybe I don't want to put my eternal damnation onto whether or not I believe in one particular thing, but I do accept all paths, I've just seen too much and learned too much tripping. As for not noticing chakra energies... Just don't look for them. If you LOOK for something you are putting the doubt in your mind already (well I can't see it right the duck now so it must not be true) just understand that you have an energy flow that is much more than your physical body. Maybe meditate on one particular chakra. Just one. Pick one at random, be daring. Say to yourself I don't know and I don't understand, but I WANT to. Focus on just that, the area of your body, or the color, or look up a definition for that particular chakra (ok I don't believe in chakra but I'm willing to give it the benefit of the doubt, what can the green heart chakra teach me?) Focus on that and let go of your doubt. Maybe it won't work for you. THE FIRST TIME. So be patient. It will work. And that day when you say to yourself holy shit... I feel it (it doesn't have to be something you see, I work on my chakra daily, doesn't mean I'm in a perpetual rainbow of color) just think to yourself that you kept an open mind and were rewarded. I hope you are able to do this and have it work for you
