A building, plot or mandala when built an enclosed, reverberated with dynamic energy. The enclosed space throbs like a living entity and contains crucial nodes called marma points.
Marma is mounted into the floor of the shell construction at the respective Marma nodal points. This is specially done with buildings, which are on the nonaxial plots or has north tilted more than 12 degrees. This correction is also used for bigger plots and spaces where generally the creation of a Vastu boundary using cosmic symbols is not possible.
