Vallabhacharya, also known as Vallabha, was a Hindu philosopher and theologian who lived in the 15th century in India. He was born in the year 1479 in the city of Champaran, located in present-day Uttar Pradesh. He is considered to be the founder of Pushti Marg Vaishnavism, a devotional sect within Hinduism.

Vallabhacharya's father, Lakshman Bhatt, was a scholar and a priest in the temple of Govind Devji in Mathura. From a young age, Vallabhacharya showed great interest and aptitude in religious and spiritual matters. He received an extensive education in Sanskrit, Vedas, and other Hindu scriptures from his father and other renowned teachers.

At the age of eleven, Vallabhacharya left home to travel and gain more knowledge. He visited various holy places and studied under many scholars. During his travels, he met and was deeply influenced by the teachings of Advaita philosopher, Shri Shankaracharya. However, he also had some disagreements with Shankaracharya's teachings, which led him to develop his own school of thought.

In the year 1493, at the age of fourteen, Vallabhacharya returned to Mathura and began teaching and spreading his philosophy. He emphasized the importance of devotion and love for God as the path to salvation, rather than renunciation or knowledge. He also believed in the concept of Shuddhadvaita or pure monism, which states that the individual soul is not separate from the divine soul.

Vallabhacharya's teachings gained popularity and attracted many followers, who became known as Pushtimargis. He also wrote several commentaries and texts, including the Shodash Granth, which is considered the main scripture of Pushti Marg Vaishnavism.

Vallabhacharya spent the rest of his life traveling and spreading his teachings throughout India. He also established several temples, including the famous Shrinathji temple in Nathdwara, which is considered the main seat of Pushti Marg Vaishnavism.

Vallabhacharya passed away in the year 1531 in Varanasi, at the age of 52. His followers continue to uphold his teachings and principles, and his legacy continues to thrive through the Pushti Marg Vaishnavism sect. His contributions to Hinduism and philosophy have had a lasting impact, and he is still revered and remembered as a great saint and scholar.
