Ganesh Chaturthi, the grand celebration dedicated to Lord Ganesha, is not just a cultural and devotional festival — it is also deeply rooted in astrological wisdom. Ganesha is worshipped because he is thought to change the energies of the planets, calm the mind, and bring good luck. He is also known as the remover of obstacles (Vighnaharta) and the lord of knowledge (Buddhi Vinayaka).
