A Janmashtami puja kit includes essential items for worshiping Lord Krishna during the festival. It typically features an idol of baby Krishna, a puja thali for arranging offerings, and fresh flowers for decoration. The kit also contains fruits and sweets, such as laddus and bananas, along with incense sticks and a diya (oil lamp) for light. Holy water, chandan (sandalwood paste), haldi (turmeric), and kumkum are included for purification and offerings. Lastly, agarbatti is provided to create a sacred atmosphere, helping devotees perform the puja rituals with devotion.
