Tulsi Vivah is considered the beginning of the wedding season in India in the month of Kartik, which occurs in October/November every year. Tulsi vivah is conducted on the day after Kartik Ekadashi (the eleventh bright day of the new moon, Amavasya). According to Hindu mythology, Tulsi is ceremonially married to Lord Vishnu on this day. The festival continues for five days and concludes on the full moon day of Kartik Poornima.
It is believed that by observing a fast on Vaikuntha Ekadasi day and spending the day in poojas and prayers to Lord Vishnu, one will be absolved of all sins and will attain Moksha and the doors of Vaikunta will be kept open for the soul after it leaves this physical body.
The Gayatri Mantra is one of the most revered and perhaps one of the most practiced mantra in Hinduism. The Durga Gayatri is a variation of the Gayatri mantra designed to address Goddess Durga, particularly during the period of Durga Navaratri or Durga Puja. The Durga Gayatri adapts the 24-syllable metre of the original Gayatri to invoke the Goddess.
