SIGNIFICANCE OF ISHTI AND ANVADHAN, IMPORTANCE OF ISHTI AND ANVADHAN
The Anvadhan and Ishti celebrations are observed on Amavasy (New Moon) and Purnima (Full Moon) respectively, of every month. On the days of Anvadhan and Ishti, Lord Vishnu is worshipped for blessings of happiness, prosperity, peace. These two festivals are auspicious and hold special significance and importance for the Vaishnav Sampradaya and devotees of Lord Vishnu.
On Anvadhan, a day-long fast is observed by devotees and they have only one Sattvik meal at the end of the day. Vaishnavites also perform Vishnu havan to receive blessings of Lord Vishnu.
The word Ishti also means desire. On this day, the devotees of Vaishnav Sampradaya perform Satyanarayan Katha or chant Vishnu’s name for fulfilment of their true desires. In the Satyanarya Katha, Lord Narayan (Vishnu) is worshipped for the wellbeing of the family. The main ritual in this puja is hearing the Satyanaryan Katha, which are different stories that glorify the powers and blessings of Lord Narayan and enhance devotion to the Lord. Devotees invite their friends and other family members to hear the Satyanarayan Katha, which is said to bring blessings of divine Lord Narayan.
On Ishti puja day, the Dasavatar (10 manifestations) of Lord Vishnu are honoured and worshipped too. Meditation and Japa/Mantra chanting of Vishnu Sahasranam and other Vedic Mantras of the divine Lord helps one to be on the path of Dharma. Donations of food, clothes etc. are made to Brahmins and the needy.
There is a general misunderstanding among some devotees that Anvadhan and Ishti are the same festival. However, they are different festivals which are celebrated on two different days of each month.
