Dr. Pillai on the Secret Science of Vedic Temples
The Yogis identified certain vortices that are capable of creating distinct vibrations necessary for living our life without limitation. There are vortices where you can feel the mind moving to a higher state of consciousness quite naturally with minimum efforts. The sanctum sanctorum of the temples carries the highest vibration. Going around those vortices will influence not only our brain but also our subtle bodies.
There are vortices where one's ego will fall apart. Certain meditation practices have been prescribed in specific vortices for the dissolution of ego. Maya, which is illusory perception of material reality, can also be diffused relatively easily in certain vortexes.
There are also vortices that promote Maya because Maya is an essential component, or essential prerequisite, for living a material life. These vortices are associated with wealth, wealth building vibrations, gentle relationships, luxury, etc.
Removing karma is very critical for our progress in spiritual life as well as material life. Although there are mantras and ritual practices for karma removal, the vortices play a key role enhancing the power of the rituals as well as the mantras. For this reason the Yogis recommended regular periodic temple visits to ensure progress in one's own material as well as spiritual life.
