(If you want to go directly to summoning an entity to aid you - skip this section and go directly to section 13 onwards).
The Preta that we have chosen for you to summon is High Priest Lavalian Gatisaman. As many Hindu Aaiyyanists know, this individual was one of the High Priests who as instrumental during the Kalaiyyan massacre to create the blood sacrifice to enable enough energy to link the Ancient incarnation of Murugan with the universal Brahman OM.
Gatisaman was a particular celebrated ancient Tantric Aaiyyanist. He was supposedly said to have formulated the Aaiyyanist Dravidian symbolic scripts and rituals in order to break the links between many different Lokas and Talas. He took the work and teachings of Murugan before him and honed the science of Dravidian symbolic magic. He was a great teacher and researcher in the Kalaiyyan Tantric school and there are still some hidden Tantric temples dedicated to him today.
Other schools of Hindu Aaiyyanist thought deem Gatisaman to be an evil individual who helped kill hundreds of thousands in a blood sacrifice. However other Aaiyyanist schools (notably the Tantric or left hand Schools) deem Gatisaman to be a great scholar and statesman. In Aaiyyanism we cannot condemn nor condone the actions of others. We must simply love all as OM.
All Aaiyyanists agree that after his death he was sent (or went voluntarily) to the Preta-Tala dimension. Before Gatisaman died he formulated the method on how he should be invoked after his death. This was actually an ancient Aaiyyanist ceremony (pre-dating Gatisaman) that Lavalian himself redesigned for his followers to perform should the need arise. Lavalian himself wrote down the inscription that you will use in section 13 and the ritual mantras that you need to chant to invoke him.
To explain the Dravidian Aaiyyanist symbolic magic would take several volumes. Suffice it to say it is a sacred language given to us from Murugan via Siva that has the ability to unlock portals between our realm and the Gods. Lavalian's inscriptions directly link this realm to the Preta Tala. If you link with Lavalian from this dimension you can direct him to help you in various ways such as directing negative energy against your enemies. However, Lavalian will eventually ask a favour from you and that favour will be determined by your past interactions with him. Yes, the fact that you area reading this now means that you have already contacted/linked with Lavalian in a previous incarnation. In fact, you have probably interacted with all the entities in this book in your previous lives, and you will know this when you contact them all and begin to remember.
