The global Hare Krishna movement, formally known as ISKCON, stands as a direct outgrowth of Gaudiya Vaishnavism, carrying its theology, practice, and devotional mood into an international arena. At the heart of this transmission is the Gaudiya focus on Radha and Krishna, especially Krishna as the Supreme Personality of Godhead and Radha as the supreme devotee, whose loving relationship in Vrindavan becomes the model for the highest form of bhakti. This devotional ideal is articulated through the Gaudiya doctrine of *acintya-bhedābheda-tattva*, the “inconceivable oneness and difference” between the Lord, the soul, and creation, which ISKCON has adopted as its central philosophical framework. In this way, the movement does not merely borrow from Gaudiya Vaishnavism; it embodies its core vision of pure, personal devotion as the supreme spiritual path.

This continuity is anchored in lineage and scripture. ISKCON situates itself within the Brahma–Madhva–Gaudiya sampradāya, tracing its disciplic succession through Chaitanya Mahaprabhu and the Gaudiya Maṭha tradition. The guru–disciple relationship, the practice of formal initiation, and the emphasis on a living paramparā all reflect Gaudiya understandings of how divine knowledge and grace descend. The scriptural canon that shapes the movement—especially the *Bhagavad-gītā* and *Śrīmad-Bhāgavatam*, along with Gaudiya biographies and teachings of Chaitanya—is received and interpreted through this lineage, preserving the distinctive Gaudiya reading of these texts.

In the realm of practice, Gaudiya Vaishnavism has given the Hare Krishna movement both its inner disciplines and its public face. The chanting of the Hare Krishna mahā-mantra, particularly in congregational form (*saṅkīrtana*), is a direct continuation of Chaitanya’s emphasis on *nāma-saṅkīrtana* as the primary spiritual practice for this age. Temple worship of Radha-Krishna deities, observance of major festivals such as Janmāṣṭamī, Gaura Pūrṇimā, and Ratha-yātrā, and the distribution of sanctified food (*prasāda*) all follow Gaudiya ritual patterns. Ethical and lifestyle disciplines—such as vegetarianism, avoidance of intoxicants, and engagement in daily devotional service—are framed as practical expressions of Gaudiya ideals of purity and constant remembrance of Krishna.

Finally, Gaudiya Vaishnavism has shaped the movement’s missionary and cultural ethos. The Gaudiya impulse to share *nāma-bhakti* beyond the boundaries of caste and birth has been carried forward in ISKCON’s transnational outreach, public kīrtans, and organized preaching. The translation and wide dissemination of Gaudiya scriptures and commentaries have made the theology and devotional culture of Bengal and Vrindavan accessible far beyond their original geographical context. Through this process, Gaudiya Vaishnavism has not only provided the doctrinal and ritual blueprint for the Hare Krishna movement, but has also inspired its effort to universalize Radha-Krishna devotion while remaining faithful to its inherited spiritual lineage.
