Without an iota of religious leaning, there cannot be any spirituality and that is what every religion teaches. Unfortunately, the man kind is (well most of them) is hell bent on trying to understand God in a logical way.
For them, everything needs to be dissected to make people understand. That is the REAL PROBLEM.
See, they have understood God, religion with the help of God and religion but they are afraid to take it to the world because they have to explain to the world scientifically.
Why are are people so oblivious to the one eye opening book, "Bhagavat Gita".
God is not to be understood. Godness- it is only to be felt and to be practiced.
