While studying the link between modern science, applied engineering and Vaastu Purush-Mandal it becomes important to consider the logical results of modern sciences and Vaastu-Shastra is not just a traditional and orthodox method,

We are discussing here the link between Modern Science and Vaastu-Purush-Mandal. By identifying the significance of deities associated with definite directions in a Vaastu-Purush-Mandal in terms of modem science, we will try to find the hidden causality relationship. It will then be easy to see how the perception in this traditional science matches with logic and results of modern science.

In all Vedic literature, symbols and similes are used as a metaphor for explaining facts and procedures. These symbols are basically 'the perfect one word expression' for the process involved. Over a period of time we have lost the meanings of these symbols and in the present era, a stranglehold of objective methods of modern science has resulted in a certain degree of ambiguity in approach to these ancient sciences. It has now become extremely important to breach this silence of tradition and the vague response of modem science.

Here, we will try to delineate the traditional narration in terms of the basic laws, logic and approach of quantum mechanics, particle physics, biochemistry and energy dynamics. For correlating the significance of Goddesses, directions, and forces in Vaastu-Purush-Mandal the following topics are very significant -flow characteristics of solar energy, geomagnetic flux, thermal variations disturbing the electromagnetic flux lines, vector analysis of two important energy fields relative to position of the sun, sub-atomic particles, thought and consciousness as energy fields, waves and vibrations.

There are two important ideas in understanding the relevance of solar energy and geomagnetic energy for a Vaastu. The first concept is based on vector analysis of the ever-changing directional solar energy field as imposed on steady North-South geomagnetic flux. The second concept tries to understand the relationship between electromagnetic flux and movement of sub-atomic particles.

Human mind has a dual combination of both positive and negative feelings (thinking) , As the great writer and psychologist Theodor Lawrence rightly said, "The thinking which guides your intelligence is more important than how much intelligence you have" and this to major extent we can call it as our inner consciousness.

As we are quite aware that energy is in it's short supply and it's optimum use is very essential. As far as processes taking place in our eco-system is concerned, the positive energy is the one that stimulates, transmit, boost, and blesses life. Negative energy is associated with processes that hinders, devastates or exterminates life.

By providing insight into nature of these energy forms ' even at micro level, Darshanshastra and its sub-branches try to fortify life-sustaining positive energy forms. In understanding Nature, traditional means employing comprehensive perception have a definite edge over known modem scientific techniques.

Vaastu-Purush-Mandal symbolically represents this incorporation of the pro's and con's of life and aids the path that can avoid the unsaid and unheard mishaps of ours and our dear ones
