Gaura Sundara Das began his spiritual journey in 1998 when he accepted Krishna as the Supreme Personality of Godhead and started actively chanting the holy names. This period laid the foundation for his deep immersion in the philosophy and practice of Krishna Consciousness. In 2004, he received initiation from H.H. Partha Sarathi Das Goswami, symbolizing his official entry into spiritual discipleship within the Gaudiya Vaishnavism tradition. Four years later, in 2008, Gaura Sundara Das received his second brahminical initiation, further deepening his understanding and practice of spiritual development.

In 2009, he joined the Mayapur Institute of Vaishnava Education in India, where he completed the Bhakti Shastri, Bhakti Vaibhava, and the first level of Bhakti Vedanta courses. This education not only deepened his knowledge of Vaishnava philosophy but also prepared him for teaching within the Krishna Consciousness movement.

Since 2012, Gaura Sundara Das has been actively engaged in individual preaching service, traveling and giving lectures in Ukraine, India, South Africa, Europe, and the USA. His preaching work includes not only teaching at the institutes of Vrindavan and Mayapur but also organizing seminars and virtual educational programs on Vaishnava philosophy. Since 2015, he has been actively practicing pedagogy, focusing on Bhakti Shastri and Bhakti Vedanta courses, contributing to the spiritual development of his students and followers.

In 2025, Gaura Sundara Das was awarded the status of Bhaktivedanta.
