In brief: Public materials can be shared with anyone. Personal Use materials are meant for you alone, with limited exceptions for your spouse and children under 21 at home. Discourses, SATs, and Initiates' and Ministers' materials are not to be shared with anyone, including family.
Public Use
Anyone can purchase these materials. All books (except Discourses), audios, and videos designated "public" may be shared with anyone.
Personal Use
These materials are intended for the exclusive use of the owner. There is a special relationship between Spirit, through the Mystical Traveler Consciousness, and you as the owner of these materials. If you allow another person to listen to or view them, you (rather than Spirit) become responsible for what that person may initiate or release as a result.
For this reason, we strongly recommend keeping Personal Use materials private and letting anyone who is interested know they can get their own copies at www.msia.org.
Personal Use materials may be shared with your spouse and with children under 21 living at home, except for Soul Awareness Discourses, Soul Awareness Teachings (SATs), and all Initiates' and Ministers' materials.
