In Buddhism, the Buddha propagated the Doctrinal principles to the Buddhists with the purpose of helping them to receive the primary benefit of living together happily up to the highest benefit, that is to attain Nibbana without the limit of class, caste, nationality or religion.

More over, they all had also to be of heedfulness. Regarding the support which the domination did to the religion it is found that King Pasenadikosala paid his respect to Buddhism by following the Buddhism by following the Buddha’s principle of teaching and supporting Buddhism with 4 necessary factors and protecting Buddhism as much as possible such as looking after the Bhikkhu’s and Bhikkhuni’s behaviours for preventing them for doing bad actions which would be of bad outcome towards Buddhim.

Regarding the accomplishment of the support between the dominion and the religion, it is found that it took place for each other’s happiness and benefit. That is to say each part gave out and received the out come arising from donation. For example, Buddhism received convenience with the four factors from the dominion such as food, cloths, permanent materials, residence, medicines and the male and female disciple who supported Buddhism.
