There are 24 Ekadasis observed by Hindus during the year. Of these Vaikunda Ekadasi celebrated in the Tamil month Margazhi (Dec-Jan) is considered very auspicious. On this day people accompany the Lord to the doors of Heaven (SorgaVasal, Sorgam - Heaven/Vasal - Doors). In all temples the Sorgavasal will remain opened on this day.
It is believed that Parvati resides at the base, Saraswati at the centre of the palm of your hand and Laksmi at the upper portion of the hand ie., fingertips. It is therefore advised that the first thing you see after you wake up in the morning is your right hand palm.
