Vaikuntha Ekadashi Mantras — Vishnu Prayers
Vaikuntha Ekadashi (वैकुंठ एकादशी) — also called Mukkoti Ekadashi — is the holiest Ekadashi of the year, when the "Gate of Vaikuntha" (Vaikuntha Dwaram) is believed to open and devotees who fast and stay awake worshipping Vishnu are granted liberation. It falls in the bright fortnight of Margashirsha/Pausha (Dec–Jan). These are the Vishnu mantras and prayers to recite through the Ekadashi fast and night vigil.
