It is in the 8th Aethyr, ZID that you will meet with your Holy Guardian Angel. The Knowledge and Conversation with your Holy Guardian Angel is an important goal of the aspiring adept. It is no less than the magical experience of your encounter with your own inner divinity -- the divine spark at the core of your being. It is fully experienced here in ZID. Up until here, you have achieved various degrees of this Knowledge and Conversation. However, here, in ZID, is where you get to meet and communion with your Guardian Angel in his/her divine form.
This Aethyr is a powerful initiation in that you will change forever. Entering this Aethyr means that you and your inner divinity are nearly one and can begin merging into a single unit.
When you leave ZID, after a successful initiation, you will be endowed with your life's purpose and your reason for incarnating. You will possess a link to your Guardian Angel that will allow you to bring forth knowledge and wisdom down from the Spiritual Plane and into the lower planes, including the physical plane -- which means it will not be uncommon to just know things about others or to hear your Guardian Angel speak to you in quiet moments. Knowledge and Conversation with your Holy Guardian Angel is nothing less than establishing a direct link to the Divine Source and being able to tap that source at will for inspiration, knowledge, help, and wisdom.
Finally by completing ZID you achieve the grade of Magister Templi (Master of the Temple) and you take on the title of NEMO (ZIM) and can go to the Garden of NEMO yourself to help cultivate other candidates on the same quest.
