Monthly Navavarana Shri Yantra Devi Puja and Maha Mrityunjaya Homam
Worship of the Goddess is very powerful to drive away and protect from all sorts of negative forces that effect people. Maha Mrityunjaya mantra of Lord Shiva / Rudra is very powerful to remove all sorts of troubles. It is good for healing all sorts of disease, and can avert untimely death. This mantra is so powerful, in fact, that it can resurrect the dead. For this reason, it is called the "mrityu samjiivana mantra" (the mantra that bring life to the dead). It is a prayer for liberation, which turns the negative forces which helps avert all sorts of negative forces and situation which hinder a person, rendering the influence to be beneficial.
Many people are effected by various dark energies and entities which are generally unseen, but which effect people more often than they have any idea. There are many negative forces which have the potential to effect people. Demons, ghosts, nature spirits, spirits and negative energies attached to a persons home, black magic and general negative energies all have great potential to effect people. When a person or an ancestor commits a selfish and harmful act in a sacred place or to a holy person (a saint in a high state of realization) this can create a particularly difficult situation which often effects the whole family due to the intense karma of doing such things. This situation is called "guru shaapa" meaning "curse of a Saint" or "tiirtha shaapa" meaning "curse of a Holy place." Of course, it is not in the nature of a Saintly person (or the many Divine beings working through a Holy place) to "curse" a person. However since their role is supreme in the world - helping souls toward their highest purpose in life leading them toward the ultimate realization - hindering their work is understood to be capable of causing great harm to a person and their descendants much more powerful than black magic or demonic attack.
