Giriyek--An ancient Buddhist village on the Pañchâna river, on the southern border of the district of Patna (see Indraśila-guha). Across the Pañchâna river is the Giriyek-hill which is the same as Gridhrakûṭa hill, the Indraśilâ-guhâ of Hiuen Tsiang (Cunningham's Anc. Geo., p. 471). The Pañchâna river is perhaps the ancient Sappini (Sarpiṇi) mentioned by Buddhaghosha in his commentary on Mahâvagga, ch. 11, p. 12. The Sappiṇi is said to have its source in the Gridhrakûṭa mountain (see Pañchananda). Giriyek is the "Hill of the Isolated Rock" of Fa Hian, but Mr. Broadley has identified it with the "rocky peak at Bihar" (Ind. Ant., I, 19).
