according to Vastu Shastra, the ritual of offering water to Shivling involves specific practices to ensure positive energy flow. It is believed that the pot used for carrying water to the temple should be filled from home, symbolizing the transfer of positive energy from the household to the divine. Similarly, the pot should not be brought back empty, as it is considered inauspicious. Instead, the water collected from the Shivling is brought back and sprinkled throughout the house, signifying the return of divine blessings and purification of the space. This act is thought to bring peace, prosperity, and harmony to the home and its residents.
