One of the most significant achievements of this Dhamma assembly and one which was to bear fruit for centuries to come, was the Emperor's sending forth of monks, well versed in the Buddha's Dhamma and Vinaya who could recite all of it by heart, to teach it in nine different countries. These Dhammadūta monks included the Venerable Majjhantika Thera who went to Kashmir and Gandhāra. He was asked to preach the Dhamma and establish an order of monks there. The Venerable Mahādeva was sent to Mahinsakamaṇḍaḷa (modern Mysore) and the Venerable Rakkhita Thera was dispatched to Vanavāsī (northern Kanara in the south of India.) The Venerable Yonaka Dhammarakkhita Thera was sent to Upper Aparantaka (northern Gujarat, Kathiawar, Kutch and Sindh].

The Venerable Mahārakkhita Thera went to Yonaka-loka (the land of the lonians, Bactrians and the Greeks.) The Venerable Majjhima Thera went to Himavanta (the place adjoining the Himalayas.) The Venerable Soṇa and the Venerable Uttara were sent to Suvaṇṇabhūmi [now Myanmar]. The Venerable Mahinda Thera, The Venerable Ittiya Thera, the Venerable Uttiya Thera, the Venerable Sambala Thera and the Venerable Bhaddasāla Thera were sent to Tambapaṇṇi (now Sri Lanka). The Dhamma missions of these monks succeeded and bore great fruits in the course of time and went a long way in ennobling the peoples of these lands with the gift of the Dhamma and influencing their civilizations and cultures.

With the spread of Dhamma through the words of the Buddha, in due course India came to be known as Visvaguru, the teacher of the world.
