The Sūtra of the Questions of Gaganagañja

The Sūtra of the Questions of Gaganagañja (Gaganagañjaparipṛcchāsūtra, Toh 148) is an important canonical work centering on the bodhisattva Gaganagañja’s inquiries to the Buddha, his display of seven miracles, and dialogue between various figures about core Mahāyāna principles. The sūtra covers topics such as the bodhisattva path, bodhicitta, concentration, buddha activity, wisdom (jñāna), as well as predictions about the future enlightenment of disciples. Throughout the discourse, the sky (gagana) is used as the central metaphor for emptiness (śūnyatā) and nonduality (advaya) to describe the nature of reality.
