The intelligence and knowledge obtained without any external source or signal and through intuition and telepathy can be called as 7th sense. I just think about Siddhas while contemplating about 7th sense. Bogar, the Siddha who made the Murugan Navabhashanam Statue of Palani Temple might have had such powers. 7th sense will help you get the knowledge about the mysterious secrets of the human mind, existence and universe. It will give the power to execute the required happenings without any source. The intuitive intellignce will help you to protect yourself from unknown and unpredicted disasters.
