The earthly religions are constantly changing their practices. Christianity, for instance, the most popular religion worldwide, has split into 200 denominations in the United States, and over 40,000 denominations worldwide. Islam, the second most popular religion on the earth, is also constantly changing. They say there are 73 Islamic schools with different understandings of the religion, and even within the different schools, there are differences. Some sects regard other sects as not being true Muslims, and on and on it goes.

It is exactly the same now as when the first humans walked the earth two million years ago, and it will be the same millions of years from now. For a traveler to distant worlds, different galaxies, and throughout the universe, the path to heavenly bliss is the same for a traveler to be at home.
