Are There Any Prohibitions When Wearing The Yantra Pendants

Are there any prohibitions when wearing the Yantra Pendants - 
say when socialising/having sexual relationship or visiting a place of death, must they be taken off and re-worn after a bath etc?

Rudra Centre does not suggest strict prohibitions when wearing Yantras Pendants but leaves it to the comfort levels of the wearer as the literature on the subject is not authoritative and indeed sometimes seems mutually contradictory. What is of utmost significance is the intention, faith and devotion of the wearer.

In general, however, it is always better to remove all sacred objects when having sex. The psychic energies generated during the act frequently interfere with the spiritual energies of the Yantra. It is also a good idea, though not mandatory, to remove them in places of death as there are intense negative and sorrow energies accumulated there. These tend to 'stick' to the Yantra and darken or dull the energies. Normal social interaction does not need Yantras to be taken off.

It is preferable to avoid getting the Pendants wet, as this will help increase the life of the plating.
