UPONATHA
There is nothing incredible in the fact that there were some customs which were commonly prevailing in Indian religious life, and uposatha was one of such customs. Here follows a study of the same in the light of the three main faiths of India, the Brahmanism, Buddhism and Jainism.

The fasting is to be observed by the sacrificer on the instruction of the priests, and as such it is the duty of the householder. Hirapyakesin 4 while dwelling upon the significance of the upavasatha, opines that the upavasatha means 'to avoid the company of impious and to seek the company of virtuous.'
