The story
Viṣṇu's heaven is Vaikuṇṭha, and its northern gate is held to stand open for this one day. Temples that have such a gate — the Paramapada Vāsal at Śrīraṅgam, the Vaikuṇṭha Dvāram at Tirumala — open it before dawn and let the queue pass through.
Every eleventh day of every fortnight belongs to Ekādaśī, the maiden the Padma Purāṇa names, and of the twenty-four the texts call this one the greatest. What this day adds is the door. An ekādaśī is otherwise kept at home; this one is kept standing in a queue, before a gate that opens once a year.
Telugu speakers call it Mukkoṭi Ekādaśī, the ekādaśī of the thirty million, because the gods are said to come down to earth that day. In Kerala the great day is Guruvāyūr Ekādaśī at the Kṛṣṇa temple there.
