The guides are always listening to your thoughts and to your heart. They are part of who you are.
You can call them by different names. At times they will respond to a name but it doesn't matter as much as how you feel inside yourself. For the guide is there to lead you to better decisions. When he hears your thought he is your conscience and your wisdom.
Surely it is your choice to hear or not, to follow or to disobey your own highest calling.
