The Kamakhya Bhairava Upasaka Foundation (KBUF), established by Shri Rajarshi Nandy, is committed to promoting authentic Śākta Dharma. The foundation aims to revive the Bhairava-tattva, emphasizing the preservation of Dharma and cultural heritage through collective spiritual practices, including the construction of Bhairava temples across India. KBUF organizes regular pūjā ceremonies, annadāna (food donation), and various seva activities at sacred sites and learning institutions, fostering community support for Sanatana Dharma.

The foundation actively engages in the preservation of spiritual heritage, conducting rituals and advocating for the safeguarding of kṣetra-s, or sacred spaces. With a mission to enhance the spiritual fabric of society, KBUF's initiatives include the Bhairava Sadhana Initiative, which encourages global participation in spiritual practices. As part of its outreach, KBUF also supports social causes, providing assistance to underserved populations and care for animals.

The foundation's vision includes establishing eight magnificent Bhairava temples to serve as spiritual and cultural pillars in the community
