A wall clock, according to Vastu Shastra, is not just a timekeeping device but also influences energy flow in your home. The ideal directions for placing a clock are the north, east, or northeast walls, as these attract positivity and growth. Avoid placing clocks in the south direction, as it may bring negativity or financial loss. Clocks should always be in working condition, as stopped clocks symbolize stagnation. Choose calming colors and clear designs, and ensure the clock is visible and easy to read. Proper placement helps maintain harmony, balance, and a steady flow of positive energy in your living space.
