As per the Hindu tradition, Diwali is considered to be a very auspicious day and involves a pooja or sacred prayer and an offering to the Gods. Different sects of Hindus perform the pooja in different ways, but the running thread through all the sects is that of lighting of diyas or lamps. The lighting of the lamp signifies the awakening of the inner Guru or consciousness in each human being as per the Hindu belief. Diyas are decorated with many artistic designs and are offered along with other pooja items like kumkum (sacred red powder), flowers, incense and food offering to the Gods and then the whole house or building is decorated with lit lamps, kept in arrays.
