Every creature in this world is consciously/unconsciously arranging place to live, move and work and pass their lives comfortably. Even a small creature like amoeba selects his place unconsciously though operated by Nature. Different living species build dwelling place according to their requirement, need and comforts. Man being self conscious species on earth has a choice to select what is the best. He has the observation of ground, place, shape, size of plot, rooms, direction, neighborhood, sources of water, natural environment, means of transport etc but is not fully aware of significance of each one of them in order to live safely, prevent troubles, and ensure happiness, prosperity and success. Vaastu as a science takes care of both external and internal factors of any structure that needs to be built.

A habitat is the birth right of every living species on earth. One of the greatest mythological figures Vishwakarma explained in detail about the science of Vaastu. The ancient wisdom of India related every work of man to higher states of consciousness in order to achieve perfection. The very perfection had been understood as Health, Harmony, Happiness; Peace, Prosperity, Success; and Personal, Professional, Social and Spiritual Excellence. This has been explained in ancient literatures of India as four fold duties of man namely Dharma (following moral and ethical codes in order to maintain life), Artha (earning prosperity and material possessions to live worldly life happily), Kama (satiating worldly desires) and Moksha (liberation or spiritual development and attainment).
