Within the tradition established by Śrīla Prabhupāda, the Bhagavad-gītā—especially in the form of his edition, *Bhagavad-gītā As It Is*—functions as the central theological and philosophical text. It is treated as the primary scripture for understanding the relationship between the soul, Kṛṣṇa, and the material world, and it lays out the core concepts of dharma, karma, renunciation, and liberation. Prabhupāda’s commentary consistently emphasizes Kṛṣṇa as the Supreme Personality of Godhead and bhakti-yoga, or devotional service, as the highest spiritual path. In this way, the Gītā provides the doctrinal framework through which all other teachings and practices are interpreted.

This text is not only a foundation for belief but also a daily guide for spiritual practice. Regular study of *Bhagavad-gītā As It Is* is encouraged for devotees, and classes based on its verses are a standard feature of temple life. Its teachings on duty, detachment, and surrender shape the ethical and devotional conduct of practitioners, informing how they work, relate to others, and orient their lives toward Kṛṣṇa. The mood of surrender and service described in the Gītā becomes the template for personal transformation.

At the same time, the Gītā serves as a principal instrument for outreach and education. It is the main text used to introduce Kṛṣṇa consciousness to the wider public, and distributing *Bhagavad-gītā As It Is* is regarded as a major form of missionary service. From children’s instruction to advanced training for leaders, the book forms the backbone of educational efforts, ensuring that the movement’s understanding of Kṛṣṇa consciousness remains rooted in a shared scriptural core. In this sense, Prabhupāda’s presentation of the Bhagavad-gītā operates as a kind of constitutional document for the community, providing both spiritual orientation and a unifying standard for doctrine and practice.
