Vallabhacharya, also known as Vallabhacharya Mahaprabhu, was a 16th century Hindu philosopher and theologian who founded the Pushti Marg Vaishnavism sect. He was born in the year 1479 in Varanasi, India and was a prolific scholar and poet who dedicated his life to spreading the teachings of Hinduism.

Vallabhacharya established Pushti Marg Vaishnavism as a path of devotion and love towards Lord Krishna. He believed that the ultimate goal of human life was to attain the grace and love of Lord Krishna, and that this could be achieved through the practice of Bhakti Yoga.

One of the key ways in which Vallabhacharya established Pushti Marg Vaishnavism was through his teachings and writings. He wrote numerous works, including commentaries on the Bhagavad Gita and the Srimad Bhagavatam, which are considered to be the foundational texts of Pushti Marg Vaishnavism. His writings emphasized the importance of surrendering to Lord Krishna and developing a deep and loving relationship with him.

Vallabhacharya also established the concept of Shuddhadvaita, which means pure non-dualism. According to this philosophy, the entire universe, including human beings, is a manifestation of Lord Krishna. This means that everything in the world is ultimately connected to and dependent on Lord Krishna. This concept forms the basis of Pushti Marg Vaishnavism, which emphasizes the importance of seeing Lord Krishna in everything and everyone.

In addition to his teachings and writings, Vallabhacharya also established a system of worship and rituals for his followers. He introduced the practice of seva, which involves offering food and other items to Lord Krishna as a form of devotion. He also established the tradition of performing the daily darshan of Lord Krishna, where devotees could see and offer their prayers to him.

Vallabhacharya also established the Pushti Marg Vaishnavism sect as a distinct and separate community within Hinduism. He appointed his son, Vitthalnath, as the head of the sect and established a system of succession where the leader of the sect would be a direct descendant of Vallabhacharya.

Through his teachings, writings, and establishment of rituals and practices, Vallabhacharya laid the foundation for Pushti Marg Vaishnavism and ensured that it would continue to thrive even after his passing. He traveled extensively, spreading the message of love and devotion towards Lord Krishna, and his followers continue to do the same to this day.

In conclusion, Vallabhacharya's deep devotion and love towards Lord Krishna, coupled with his teachings and establishment of rituals, played a crucial role in establishing Pushti Marg Vaishnavism as a distinct and influential sect within Hinduism. His contributions continue to inspire and guide his followers towards a path of devotion and love towards Lord Krishna.
