The Maṅgala Sutta (Burmese: မင်္ဂလသုတ် Mingala Thok, Thai: มงคลสูตร, Khmer: មង្គលសូត្រ mongkhol sut, Sanskrit: mahāmaṅgalasūtra, "महामङ्गलसूत्र", Standard Tibetan: བཀྲ་ཤིས་ཆེན་པོའི་མདོ།) is a discourse (Pali: sutta) of the Buddha on the subject of 'blessings' (mangala, also translated as 'good omen' or 'auspices' or 'good fortune'). In this discourse, the Buddha describes 'blessings' that are wholesome personal pursuits or attainments, identified in a progressive manner from the mundane to the ultimate spiritual goal. In Sri Lanka this is known as Sinhala: මහා මංගල සූත්රය "Maha Mangala Sutta" and this sutta considered to be part of "Maha Pirith".
This discourse is recorded in Theravada Buddhism's Pali Canon's Khuddaka Nikaya in two places: in the Khuddakapāṭha (Khp 5), and in the Sutta Nipāta (Sn 2.4). In the latter source, the discourse is called the Mahāmangala Sutta. It is also traditionally included in books of 'protection' (paritta). It is also found in the Tibetan Canon, in the Kangyur (བཀའ་འགྱུར།).
The discourse was preached at Jetavana Temple in answer to a question asked by a deva as to which things in this world could truly be considered blessings (mangalāni). The sutta describes thirty-eight blessings in ten sections, as shown in the table below:
The post-canonical Pali Commentary  explains that at the time the sutta was preached there was great discussion over the whole of Jambudvipa regarding the definition of blessings. The devas heard the discussion and argued among themselves till the matter spread to the highest Brahmā world. Then it was that Sakka suggested that a deva should visit the Buddha and ask him about it.
This sutta is one of the suttas at the preaching of which countless devas were present and countless beings realized the Truth.
