Guruvayur Ekadashi
Ekadashi, the eleventh day of every lunar fortnight, is very auspicious to the Hindus. Of the 24 Ekadashis in a year, the Vrishchika Ekadashi (Sukla paksha) has got special significance in Guruvayur temple. A memorial honour for Gajarajan Keshavan is conducted in Guruvayur. The Karanavar or head of the elephant family places a wreath at the statue of Keshavan in front of Sreevalsam guest house and all the other elephants stand around and pay obeisance. On Ekadashi day, the Udayasthamana Pooja (dawn to dusk pooja) is conducted by the Devaswom itself . After the morning seeveli, on Ekadashi there is a grand elephant procession to the Parthasarathi temple since it is regarded as Geethopadesam Day also. On Ekadasi after night pooja, the famous Ekadashi Vilakku with elephant procession takes place and provides a fitting finale to the festival.

Chembai Sangeetholsavam
Chembai Sangeetholsavam is an annual Carnatic music festival held in Guruvayur by the Guruvayur Devaswom as a kind of homage to Chembai Vaidyanatha Bhagavatar, one of the titans of Carnatic Classical Music. Chembai had conducted the festival in the temple town on his own for about 60 years. He used to invite all the great Carnatic Musicians to perform in the temple town and in course of time, the scale of the festival rivalled the Thyagaraja Aradhana at Thiruvaiyaru, which is recognised as one of the most important festivals of homage paid to Saint Thyagaraja.

The Guruvayur Devaswom decided to take charge after his death in 1974, and renamed it as Chembai Sangeetholsavam in his memory. About 2000-2500 musicians participate in this festival every year, and it is held for about 12–15 days culminating on the Guruvayur Ekadasi day, when all the musicians sing 5 favourite songs of Chembai and also the Pancharatna Kritis of Thyagaraja.

Guruvayur Temple

The Guruvayur Temple is a famous Sri Krishna temple and is one of the most important places of worship for Hindus and is often referred to as "Bhooloka Vaikuntam" which translates to the holy abode of Vishnu on Earth. The divine idol installed here represents the enchanting form of Bhagvan Vishnu endowed with the four lustrous arms carrying the conch Panchajanya, the discus Sudarshana Chakra, the mace Kaumodaki and the lotus. Adorned with the divine Tulasi garland the idol represents the majestic form of Maha Vishnu as revealed to Vasudeva Anakadundubhi and Devaki at the time of Krishna Avatar. The presiding deity in the sanctum-sanctorum is Mahavishnu. He faces east and his idol is 4 ft tall. Even though this is not a much small idol, devotees consider him as Little Krishna. He has 4 hands : The upper right hand holding chakra, lower right hand holding lotus, upper left hand holding shankha and lower left hand holding gada. He is worshipped according to the pooja routines laid down by Adi Sankaracharya and later written formally in the Tantric way by Chennas Narayanan Namboodiri (born in 1427). The Chennas Namboodiris are the hereditary Tantris of the Guruvayur temple. The temple/pooja routines are strictly followed without any compromise. The Tantri is available full-time at the Temple to ensure this. The Melsanti (Chief Priest) enters the Sri Kovil (sanctum sanctorum) at 2:30 AM and does not drink even a glass of water up to the completion of noon poojas at 12:30 PM. The vedic traditions being followed here with absolute perfection and sincerity is the hallmark of the Guruvayur temple. It is important to note here that, even though the shrine is considered to be one of the holiest spots for Vaishnavites, the temple is not a part of the 108 Divya Desams. There are sub-shrines for Ganapathi, Ayyappan and Bhagavathi inside the complex, and also two shrines for Ganapathi and serpent deities under the temple outside the complex.
