"Civilization is static unless there is spiritual movement. The soul moves the body, and the living body moves the world. We are concerned about the body, but we have no knowledge of the spirit that is moving that body. Without the spirit, the body is motionless, or dead."
-- "Science of Self Realization"
by His Divine Grace A.C. Bhaktivedanta Swami Prabhupada
After reading this quote of one of my favorite books, most would think that the author of such book is some sort of Judeo-Christian theologian, philosopher or at least writer. The use of the word "spirit" is so loose in religion that it may refer to the Holy Spirit (Christianity), the spirit of God, a person's soul as a synonym, a ghost or other life force. Hence a Christian might conclude that the author refers to the Holy Spirit. We could understand it as, "Without the [Holy Spirit], the body is motionless, or dead."
The text above is actually from my favorite book on Krishna -- "Science of Self Realization" by His Divine Grace A.C. Bhaktivedanta Swami Prabhupada (http://www.iskcon.org/).
The concept of the Godhead is shared by many religions. It was actually reading this book that I understood that all living creatures exist to accomplish a common will of God.
"We living entities, being parts and parcels of God, are dutybound to serve Him."
-- "Science of Self Realization"
by His Divine Grace A.C. Bhaktivedanta Swami Prabhupada
This common concept explains our function in God's creation. Of course, there are other details in Krishna that don't apply to the three Abrahamic religions (Judaism, Christianity and Islam). Hence I'm not interested to talk about them here.
At the same time, in the same book we can see the common belief that we must accept God in our lives.
"God is there, and we can see Him at every moment. If we refuse to see God in our life, then He will be present before us as cruel death. If we do not choose to see Him in one feature, we will see Him in another."
-- "Science of Self Realization"
by His Divine Grace A.C. Bhaktivedanta Swami Prabhupada
Once again, it may feel confusing to understand that these quotes that I'm using here are Krishna -- a religion that we -- Christians -- tend to see as Pagan or even ungodly. Of course, at the end of the day there's only one God and we -- humans -- have given Him different names. Then again, Christianity may be derived from the same core concepts of a common ancient and forgotten religion or mere group of beliefs. This latter can be highly rejected by many, but understood by those who aren't too blind or stubborn.
