Abstract

A critical review of five articles that appeared in the special issue of Acta Asiatica, i.e. • Saitō, Akira. “Avalokiteśvara in the Prajñāpāramitāhṛdaya.” • Watanabe, Shōgo. “The Lineage of the Prajñāpāramitāhṛdaya: With a Focus on Its Introduction and Expressions of Emptiness.” • Horiuchi, Toshio. “Revisiting the ‘Indian’ Commentaries on the Prajñāpāramitāhṛdaya: Vimalamitra’s Interpretation of the Eight Aspects.” • Ishii, Kōsei. “The Chinese Texts and Sanskrit Text of the Prajñāpāramitāhṛdaya Seen by Wŏnch’ŭk 円測.” • Silk, Jonathan A. “The Heart Sūtra as Dhāraṇī.” My overall impression of Frontier is that the authors are committed to a hermeneutic dictated by the Buddhist religion itself, that the Heart Sutra is an Indian text, composed in Sanskrit. The articles in Frontier seem to suggest that no counterfactual evidence exists, or could exist, that would change this conclusion.
