Ayadi Vastu is a specialized branch of Vastu Shastra that focuses on precise mathematical calculations to ensure harmony and balance in building design and spatial arrangements. It emphasizes the use of Ayadi principles, which include six key factors: Vara (weekday), Tithi (lunar day), Nakshatra (constellation), Ayana (solstice), Masa (month), and Ritu (season), to determine the most auspicious measurements and orientations for construction. By aligning a structure with cosmic energies, Ayadi Vastu enhances the flow of positive vibrations, fostering prosperity, health, and spiritual well-being for its occupants. This science integrates ancient wisdom with practical design to create spaces that resonate with universal harmony.
