This verse, delivered by Yājñavalkya to his wife, Gārgī, establishes a profound principle of authority rooted in realized knowledge. The declaration, “You are worthy to expound all that; there is no knower apart from you,” transcends mere deference and signifies a recognition of her direct experiential understanding. This is not blind faith, but an acknowledgement of the transformative power of samādhi – a state of profoundly concentrated awareness – which has rendered her uniquely qualified to articulate the complex truths of the Yoga Yājñavalkya. The phrase “with the mind perfectly concentrated on it” underscores the necessity of mental discipline, a foundational element in any path of dhyāna, highlighting the importance of sustained focus for genuine insight. It establishes a model for the student-teacher relationship within the yogic tradition, where the teacher’s authority stems from their own realized state, not simply their position.
