In south cows are offered special veneration as they are supposed to be the incarnation of Goddess Lakshmi and therefore they are adorned and worshipped on this day .
On second day there is a traditional practice specially in Maharashtra of taking bath before sunrise with oil and "Uptan" (paste) of gram flour and fragrant powders.In northern India, especially in places like the Punjab, Diwali is dedicated to the worship of Lord Rama. While in Bengal, Kali/Durga, the goddess of strength, is worshipped? This reverence is called "Kali Chaudas or Kal Chaturdasi". It is believed that on this day kali killed the wicked Raktavija. Lord Ganesha, the elephant-headed god, the symbol of auspiciousness and wisdom, is also worshipped in most Hindu homes on this day. Kerala is probably the only state in India where even Hindus do not celebrate Diwali. The major festival there is Onam. To the Jain's, Deepavali has an added significance to the great event of Mahaveera attaining the Eternal Bliss of Nirvaana. The passing into Eternity on the same Amavasya of Swami Dayananda Saraswati, that leonine sanyasin who was one of the first to light the torch of Hindu Renaissance during the last century, and of Swami Ramatirtha who carried the fragrance of the spiritual message of Hindu Dharma to the western world, have brought the national-cum-spiritual tradition of Deepaavali right up to modern times.
Govardhan-Puja is also performed in the North on the fourth day. This day is also observed as Annakoot meaning mountain of food. In temples especially in Mathura and Nathadwara, the deities are given milkbath, dressed in shining attires with ornaments of dazzling diamonds, pearls, rubies and other precious stones. After the prayers and traditional worship innumerable varieties of delicious sweets are offered to the deities as "Bhog" and then the devotees approach and take Prasad. Goddess Lakshmi is worshipped in every Hindu household. In many Hindu homes it is a custom for the wife to put the red tilak on the forehead of her husband, garland him and do his "Aarathi" with a prayer for his long life. In appreciation of all the tender care that the wife showers on him, the husband gives her a costly gift. This Gudi Padwa is symbolic of love and devotion between the wife and husband. On this day newly married daughters with their husbands are invited for special meals and given presents. Diwali celebration is a very happy occasion for all.
