" Mauryan empire towards the satrapies of Gedrosia part of which were ceded by Seleucus to Chandragupta. The discovery of the remains of a large Buddhist sanctuary on "Koh-i-Khwaja" in Sistan suggests that this province also was perhaps included in the Mauryan empire, and the Buddhist influence reached there in the time of Asoka himself."
Further south, that Jaz Morian Lake have marked this side the western boundary of the Mauryan empire. As the name suggests, this place commemorates some signal victory or achievement of the Mauryan emperors. It may be the construction of the lake itself like the big Sudarsana lake by Chandragupta further east in Kathiawad"

Pg.5 : In relation to his predecessors, he was the first Indian king to rule over an empire embracing much of India and its western borderlands, from Afghanistan to Orissa and towards the south as far as Karnataka. In relation to the rulers who followed him, it was his example which influenced thought-philosophical, religious, cultural-in Asia more profoundly than that of any other political figure of antiquity."

↑" Pg.42-43 : We thus obtain a fairly accurate idea of the extent of Asoka's dominions. They included the whole of India except the southern extremity of the peninsula held by the Choda, Pandya, Satiya- putra and Keralaputra kings. This southern boundary is marked roughly by a line drawn from Pulicat near Madras in the east, to Gooty and Chitaldrug in the north where the four copies of Aśoka's Minor Rock Edicts have been discovered right up to the northern point of the South Canara District on the west. Let us now see what Greek princes have been mentioned by Aśoka as his contemporaries, and try to identify them. They have all been named in Rock Edict XIII. Of course, Amtiyoka is the first to be named as he was a neighbour of Asoka. Beyond his kingdom, we are told, were ruling the four princes Turamaya, Amtekina or Amtikini, Maga and Alikasumdra. Amtiyoka is, of course, Antiochus II. Theos (B.C. 261-246), king of Syria, and Turamaya, Ptolemy II. Philadelphos of Egypt (285-247). Amtekina or Amtikini, as Bühler has remarked, corresponds to the Greek Antigenes rather than to Antigonus."Bhandarkar, D. R. 《 Asoka》、Central Archelogical Library、第42−43頁 ISBN: 978-93-837-2346-1.

Asoka, the greatest of the Mauryan emperors, took power in 272 BC and extended the empire from Afghanistan to Assam and from the Himalayas to Mysore, leaving behind a series of inscriptions recording his edicts on pillars and rocks across the continent."
