Place the Ganpati idol on an elevated wooden plank in the northeast direction of your home to bring good luck and fortune. Make sure you do not position the Ganesh idol in the south direction or even under the staircase, as it is considered inauspicious. Place Kalash with rice, turmeric, kumkum, sandalwood, and organic grass near the idol. Decorate with flowers and light diyas and incense sticks to usher positivity into the home.
