SahasraMahavaastu: Tantra-Vaastu: The base of the Tantra Vaastu is related to the emergence-excitation and balancing of the five great elements,through the cosmic designs-chants-colours and auspicious time ,so the ascending helical curve of energy gets unified with the cycles of Time and effectively fruition of the guided desire succeed in to the completion leading to the accomplished state of the mind . In this figure we can see the essence of such formations through the unified expression of the colours and geometric figures .Red colour is related to the fire element and pink shade reflects a combination of royal and divine fire element.In correlation to the fire that leads to ash ie Earth element is signified by the black colour but this black formation being square and in a perfect geometry,it's related to the subtle divine vibrations of the earth element."Earth when becomes a container it holds and collects the water "is signified by the white circular geometry in the heart of the earth formation.White colour with circular formation is the unified statement of the wind and water element.Where unification of wind and water happens there descend the grace of the ether-sky.This descend of the cosmic energy is the purpose of the Tantra ;which can be learnt in this simple geometric colourful formation.This can be said as the beginning of the learning of Tantra-Vaastu.
