I think if you are not a Christian and are not attached to this egregor, then it does not matter.
Orthodox Christians are baptized from right to left, while Catholics are on the contrary. At first Catholics too were baptized from right to left, but then they began to do this action from left to right.
Oh, if you're trying to learn the sign to get be friendly with some Christians, avoid the term
egregore .
Why? After all, I do not see anything wrong or offensive in this. Egregor is a designation of a large energy information space created by a large group of people and it can be not only Christian.
