Question: In this Vinaya, overnight chanda is invalid. If the signs of dawn are not yet clear and the karman has concluded, but the upoṣadha recitation or the pravāraṇā has not yet concluded, may it pass into dawn? Answer: It is invalid. Thus, in the Mahāsāṃghika-vinaya: if seventy thousand or eighty thousand people perform pravāraṇā and fear the appearance of the signs of dawn, they should reduce the assembly and perform pravāraṇā outside the boundary. In the Dharmaguptaka Vinaya: if the signs of dawn are about to appear, an abbreviated upoṣadha recitation is allowed. Thus we know that overnight chanda cannot cover the matter being undertaken.
