Vishnu Puja Yagya is a Hindu ritual that is performed to offer prayers and seek blessings from Lord Vishnu, who is considered as the preserver of the universe in Hinduism. This yagya is typically performed by devotees who seek protection, well-being, and spiritual upliftment.

The Vishnu Puja Yagya involves the recitation of Vedic mantras, the offering of various items such as flowers, fruits, and sweets, and the lighting of lamps and incense sticks. The ritual is performed by a priest or a group of priests who are well-versed in the Vedic scriptures and traditions.

The yagya is usually performed on special occasions such as birthdays, weddings, or any other important event in a person's life. It is believed that performing this yagya with devotion and sincerity can help to remove obstacles and bring peace and prosperity in one's life.

Devotees can also participate in the yagya remotely by sending their prayers and offerings through a priest or a yagya service provider. This way, they can benefit from the blessings of Lord Vishnu and seek his divine intervention in their lives.
