Occult tattoos
Actually, all the tattoos that exist for a very long time and appeared at ancient times are occult and ritual. Such peculiarity of these is conditioned with the culture of ancient people and purposes they used the tattoos in. The tattoos weren't just a decoration for ancient people it was means of communication with gods, means of protection and so on and so forth. Nowadays a great number of the occult and ritual tattoos used as decorative images and that extremely wrong as these are the tattoos of peculiar occult meaning and so may not be patterned just like that.
First of all one should no that those intricate images are not just images and they exchange certain information. Say, the popular tattoo of burning heart has to be patterned only on the certain part of one's body as it is a catholic symbol of Jesus' sacrifice for sake of people and such tattoo means that a person greatly appreciate for him. So, such tattoo may in no case be a tattoo of people of another religion as it will be a reveal that they neglect their god and trust in Jesus.
The pentagram is common tattoo of those who follow the devil. Though it is cute and mystic one may not has it on his or her body just like decoration. Moreover, on the position of pentagram depends the meaning of that. Say, if one has the pentagram with two points up it means that he appreciates the beast and the pentagram with one point up means that a person appreciates the Devil.
The ritual tattoos can't be placed on any part of a body. Each of those has its peculiar place to be patterned on. Even the smallest deviation of its situating will totally change the meaning of tattoo and may result in inevitable sequences. The ritual, occult and protective tattoos are the tattoos to be hide from public eye. Those are tattoos that are patterned in order to express belonging to some culture or community. Those are signs for gods and spirits but not for people and sure those are not a decoration.
So, if one has a ritual or occult tattoo his or her friends will never see it as it is usually patterned on place hidden from public eye. The process of tattooing of ancient times was rather painful process. There were no special equipment for tattooing and so tattoo was patterned by means of cutting the skin and rubbing in some kind of colour. There is no way fro a person to undergo such pain without any visible reasons. So, that is an argument to weigh that ancient tattoos were the tattoo of peculiar mystical meaning and function.
If you the crosses or other religious symbols on somebody's body be sure that those are just decorations and are of no peculiar meaning. People who identify their belonging to certain culture or community will never have the tattoo on body places visible for the public eye. And, if you want to have a tattoo think carefully about the tattoo you want and find out whether it is not the occult or ritual tattoo as those will influence you life and may result in its took a turn to worse.
