What do you mean by externally? This is not the correct line of thinking. Basically, it was described by others that such mantras cannot be used in a manner that is totally detached from yourself, but this is not something someone would do often.
Examples of this would be like if you curse someone, or if you are trying to do something for another person, like bless them.
In these cases, you want the energy directed away from you, but apparently this is not possible with these mantras (I have not seen or recall any detailed information on the matter).
These examples are different than if you are trying to create material changes in the world, which would still be linked to your soul. This could take the form of trying to generate wealth, or maybe improve your family life, or something like that. They are external, but also linked to your soul, and there is no problem with such items being linked to you, unlike a curse or other negative energies.
So, I don't have enough information on exactly what you were doing, but I think there is a possibility you were ok using the mantra. Hopefully the information here should help clarify this, or you should ask your GD about this.
