According to Vastu Shastra, the ancient Indian science of architecture, the direction of water flow significantly impacts the energy flow around a dwelling. A river flowing towards the south direction from a house is generally considered inauspicious. In Vastu, south represents the direction of Pitru (ancestors) and Yama (Lord of Death). The continuous flow of water towards the south can create an imbalance in the energies, potentially leading to challenges related to health, wealth, and family relationships. It is advisable to carefully consider this aspect before making a decision to purchase a property located near a river.
