There is a psychic fair in Tektite bldg. (Phil Stock Exchange Centre) on March 15-17 from 10am-7pm.
About the kulam/gayuma, the most fundamental still is love/compassion, honestly speaking. In black magic and the like, articifial elementals are created either to injure the target of the creator. For this to work, the artificial elementals must be able to attach themselves akin to viruses, and to be able to do that they must find vibrations synchronous to them. For example, a "hate" elemental can only attach itself to a hateful person. Otherwise, it will go back to the its creator, doing imposing its harmful way to him. This also is the mechanism for positive artificial elemental such as a mother's intention to protect her son during a voyage or the like.
Actually, everyone creates artificial elementals with their thoughts and emotions, only blkack magician and/or light workers mostly can focus their thoughts to make their artificial elementals more powerful and concentrated.
Hope this helps!
