Shri Mataji: Yes there are, there are mantras which are according to the centers, which are in trouble.
For example, this is the center between the optic chiasma, is the center of Christ. So now, if the Kundalini has stopped at that point, then you have to take His name, and it opens up. But you have to be a Realized soul first of all. You must have the authority. Then it opens out that center. So for every center there is a different deity. And at that center we have to take that particular name. It’s nothing haphazard, it is very scientific.
