The Buddhist Sangha was indeed an organization of monks. This means that option 1 is correct. The Sangha was primarily comprised of Buddhist monks who dedicated their lives to the practice of Buddhism. They followed the teachings of Buddha and lived in monastic communities. These monks were considered the spiritual leaders of the Buddhist community and were responsible for preserving and spreading the Dhamma, which refers to the teachings of Buddha. They played a crucial role in educating and guiding others in the path of Buddhism. However, it is important to note that while the Sangha may have indirectly contributed to the spread of education and may have provided relief to the poor in times of distress, these were not their primary purposes or functions. Therefore, options 2 and 4 can be eliminated. The integration of the state, as mentioned in option 3, is not directly related to the role of the Buddhist Sangha. Hence, option 3 can also be eliminated. Overall, the correct answer is option 1, as it accurately describes the role of the Buddhist Sangha as an organization of monks who became teachers of Dhamma.
