The festival joins intimate home worship with a great public celebration — from the quiet installing of a clay murti in the household to the vast processions of the visarjan.
Pranapratishtha — installing the murti
The festival begins by bringing home a clay murti of Ganesha and performing pranapratishtha — the invocation that invites the living presence of the deity into the image. From that moment the murti is treated as an honoured guest in the house for the days of the festival.
Shodashopachara puja
Ganesha is worshipped with the sixteen traditional services (shodashopachara) — seat, water for the feet, bath, garments, sacred thread, sandal paste, flowers, incense, lamp, food and so on — offered with devotion each day, often morning and evening.
Modaka naivedya
The food offering dearest to Ganesha is the modaka — a sweet dumpling of rice flour filled with jaggery and coconut — which is why he is fondly called Modakapriya. Twenty-one modakas are a customary offering, along with durva grass, which he also loves.
Atharvashirsha and Sankashti recitation
Devotees recite the Ganapati Atharvashirsha (the Upanishadic hymn to Ganesha) and observe Sankashti vrata. Through the days the names and stotras of Ganesha are chanted, keeping the household turned toward him.
The sarvajanik (public) utsav
Alongside home worship, large community pandals host a public Ganesha. The freedom fighter Lokmanya Bal Gangadhar Tilak is credited with reviving Ganesha Chaturthi in the 1890s as a sarvajanik (public) festival in Maharashtra — a way to gather people across communities for cultural and national awakening. Much of the festival’s public, ten-day form today follows from that revival.
Eco-friendly clay murti
The older and traditional practice is a murti of natural, unbaked clay (shadu) with natural colours, which dissolves cleanly in water. Many today return to such eco-friendly murtis — and to home or tank immersion — to keep the visarjan gentle on rivers, lakes and the sea.
Visarjan — the farewell
On the last day the murti is carried in procession and immersed in water (visarjan), symbolising Ganesha’s return to the formless and the cycle of arrival and departure. The crowds send him off with the cry “Ganpati Bappa Morya, pudhchya varshi lavkar ya” — “Lord Ganapati, come again soon next year.”
Behind the beloved form lies a rich symbolism. A few of the best-known aspects of Ganesha and what the tradition reads in them:
Prathama Pujya — worshipped first
Ganesha is the Prathama Pujya — the deity invoked before any undertaking, worship or ceremony — for he is Vighnaharta, the remover of obstacles, and Vighneshvara, their lord. To begin with Ganesha is to ask that the path ahead be cleared.
Ekadanta — the single tusk
Ganesha is Ekadanta, the one-tusked. In a well-known account he broke off one of his tusks to use as a pen so as not to pause while writing down the Mahabharata as the sage Vyasa dictated it without stopping — a sign of his role as patron of learning and unbroken effort.
The mushaka — the mouse vahana
His vehicle is the mushaka, the mouse — small yet able to reach everywhere and gnaw through every barrier. The great elephant-headed lord riding the tiny mouse is read as wisdom mastering desire, and the large holding sway over the small.
The elephant head — buddhi and wisdom
The elephant head is read symbolically: the large head for great intellect (buddhi), the wide ears for listening well, the small eyes for focus and discernment, and the trunk for the discrimination that can be both powerful and delicate. Ganesha is thus the very image of wisdom (buddhi) and discernment.
Sankashti Chaturthi (monthly)
Beyond the annual festival, the Chaturthi of the waning moon each month is kept as Sankashti Chaturthi — “the fourth that removes difficulty.” Devotees fast through the day and break it after sighting the moon and offering worship to Ganesha in the night.
Angaraki Chaturthi
When Sankashti Chaturthi falls on a Tuesday (Mangalavara / Angaraka, the day of Mars), it is called Angaraki Chaturthi and is held to be an especially powerful day for Ganesha vrata.
