113:3.1
One of the most important things a destiny guardian does for her mortal subject is to effect a personal co-ordination of the numerous impersonal spirit influences which indwell, surround, and impinge upon the mind and soul of the evolving material creature. Human beings are personalities, and it is exceedingly difficult for nonpersonal spirits and prepersonal entities to make direct contact with such highly material and discretely personal minds. In the ministry of the guarding angel all of these influences are more or less unified and made more nearly appreciable by the expanding moral nature of the evolving human personality.
