Ekadasi, the eleventh day of every lunar fortnight, is very auspicious to the Hindus. Of the 24 Ekadasis in an year, the Vrishchika Ekadasi (Suklapaksha) has got special significance in Guruvayur. It falls in the Mandala season. The Navami (9th day) and Dasami (10th day) are also very important. Ekadasi Vilakku starts a month before the Ekadasi day as offerings by different persons, families and organisations.
On Navami day, the Vilakku is lit with ghee as an offering by Kolady family. The Dasami Vilakku which used to be an offering of Zamorin Raja, is now conducted by Guruvayurappan Sankeerthana Trust. After the temple is open on this day for Nirmalya darshan ( 3.00AM ), it is closed only at 9.00 am on Dwadasi Day (12th day), thus allowing continues darshan for devotees throughout Dasami and Ekadasi Days. Until the temple entry for all Hindus in 1947, Avarnas (lower caste) were allowed to come up to Thiyyarambalam on Dasami day (in between Manjulal and Eastern Gopuram).
On Dwadasi day there is a custom of offering a token amount called Dwadasi Panam in Koothambalam for the welfare of the family. A highlight of the Ekadasi is the memorial honour for Gajarajan Kesavan . The Karanavar or head of the elephant family places a wreath at the statue of Kesavan in front of Sreevalsam guest house and all the other elephants stand around and pay obeisance. On Ekadasi day, the Udayasthamana Pooja (continuous pooja) is conducted by the Devaswom itself.
After the morning seeveli, on Ekadasi there is a grant elephant procession to the Parthasarathi temple since it is regarded as Geethopadesam Day also. On Ekadasi after night pooja the famous Ekadasi Vilakku with elephant procession takes place and provides a fitting finale to the festival.
