Lord Ganesh is fastly becoming universal. Even some non-Hindus and non-religious people keep his idol at homes and offices. ( I have six in my center and a Christian friend of mine has a huge Ganesh idol collection at home) Known as God of wisdom, he is remembered at least during any auspicious beginnings … and of course on his birthday
Majorly attributed to Tilak’s effort in 1890’s, Ganesh Chaturthi was popularized as a national festival in order to bridge the gap between Brahmins and 'non-Brahmins' and find a context to generate nationalistic fervor among people in Maharashtra against the British colonial rule. Whatever may be the intent, it still unites the nation and is celebrated worldwide by the believers.
Traditionally, the Ganesh idol was sculpted out of earth and returned back to the Earth by immersing in a nearby water body symbolizing a ritual send-off to his house at Kailash ( he supposedly takes away all our misfortunes with him) This cycle represented the cycle of creation and dissolution in Nature. Nice concept. But commercialization over the years made the vendors resort to Plaster of Paris and other harsh chemicals thereby polluting the environment.May be its time we did our bit to preserve other life forms We could try to use natural clay or paper based idol or better still to use a permanent idol and have a symbolic immersion.
It's just a suggestion. Whatever may be your choice, have a happy Ganesh Chaturthi
