Từ Điển Thuật Ngữ Phật Học Hán Ngữ
au! An exclamation, e.g. Ho! Oh! Ah! Also 阿傴; 阿嘔; 阿漚 or 阿優. The two letters a and u fell from the comers of Brahmā’s mouth when he gave the seventy-two letters of Kharoṣṭhī, and they are said to be placed at the beginning of the Brahminical sacred books as divine letters, the Buddhists adopting 如是 ‘Thus’ (evam) instead.
