Banerji, Bengal, p. 29. First half of 11th century, disciple of Maitrīpāla. Herukasādhana is among his works. This work would seem to be the Hevajrasatvavikāśa by Divākaracandra listed in Bandurski, p. 76 (no. 3 in the list; no 4 in the list); other works by the same author listed here are: Hevajrasādhanajñānapradīpa, Cittaviśuddhi, Hevajrabalividhi, Paramagambhīrottānakrama and Nairātmyāsādhana).
KCDS, p. 132. Sanskrit palmleaf manuscript now belonging to Potala. Title: Śrīherukākhyakāyavivekakṛtiriyam Mahāpaṇḍitācārya Śrī Divyākaracandrapādānāṃ.
I wonder if it might be his name in Apabhramśa form Siri Divāarcanda in colophon to a 1101 CE manuscript. Schaeffer, Dreaming, p. 103.
