On the third day of Diwali, people perform Lakshmi puja. The day is most important as it is entirely devoted to the adulation of Goddess Laxmi. On this very day the sun enters in its second course & passes Libra that is signified by the scale or balance. Therefore, the design of Libra is said to have the balancing of accounts & their closing. Besides the fact that the day falls on the darkest fortnight (Amavasya), it is regarded as the most propitious.
The day signifying Lakshmi Puja falls on Amavasya. The strains of blissful bell ringing and drums float from the places of worship as the priest invokes Lakshmi in an astonishing sacred ‘pouring-in’ of his heart. In a moment that unfathomable darkness is pierced by immense rays of light for just a moment & the next moment a combustion of light moves down to earth from the heaven as shimmering footed Deep-Lakshmi alights on earth in all her divine glory amidst chanting of mantras and Vedic hymns.
An ambrosial light of knowledge fallen upon humanity & this self-enlightenment is articulated through the illuminating lamps that light the houses of people. It is said that on this day Deity Laxmi walks through the lush fields & loiters through the bylanes & pours her blessings upon people.
Lakshmi Puja or the adulation of the Deity of wealth is the foremost occasion of Diwali in North and West India. It is tremendously significant to keep the houses clean and light diyas on Diwali. It is believed that Goddess Laxmi likes cleanliness and she visits the houses most that are clean. This is the foremost reason why broom is revered. Lamps are lighted in the evening to welcome the Deity. This is believed that lighting the lamps will light up her path.
Lakshmi Puja on Diwali is a combination of worship of five deities - in the beginning of puja, Lord Ganehsa is worshipped as Vighnaharta. Goddess Laxmi is adulated in her three forms - Mahalakshmi, Mahasaraswati and Mahakali.
