Vastu and Astrology
Vaastu Shastra is a developed branch of Indian Astrology for science of dwelling/architecture. They are the only part those are closely related to each other. Vaastu is interrelated with astrology. While buying a land, or making a building, entering a new house or office, we consider the "Muhuratha", timings of starting of constructions, inauguration of house or commercial buildings. All these things also depend on the horoscope of owner of land and building. Set up the doors, and other concerned things also should be done accordingly. All such knowledge, we get from the astrology and all these information's are necessary for us to have a peaceful, happy, healthy and wealthy life. Vaastu Shastra and Astrology has a great significance in our life and both Shastra provide maximum benefit and safety to the nature and environment around us.
Vaastu and Astrology are not directly connected but both have inherent symbolic relationship where one compliments the other. Although, Astrology is primarily concerned with influence of planets, their transits in different Zodiac/natal charts and their subtle influence ( positive or negative) on the human life affairs, still it's inclusive of the principles of the Vaastu-Science of Directional forces. As we know each planet, zodiac and star has a ruling planet and direction so we can say that Vasstu is an extension or manifestation of the Astrological principles of planetary energies in cosmos.
