One of the four wives of Magha. When Magha and his companions were building a rest house for travellers, they did not wish women to have any share in the work. However, Sudhammā bribed the carpenter, who made a pinnacle of seasoned wood for the building and laid it aside with the words: “Sudhammā nāma ayaṃ sālā.” When the time for the erection of the pinnacle came, he told Magha and the others that it was impossible to make a pinnacle then, as it must be of well-seasoned wood. A search was started for a seasoned pinnacle. Sudhammā agreed to give hers if she were allowed a share in the building. The men were at first unwilling, but in the end gave their consent.

After death, Sudhammā, was born in Tāvatiṃsa, and, because of her merit in the past, there came into being for her Sudhammā, the Moot Hall of the Devā, nine hundred leagues in extent (DhA.i.269 f., 274 f; J.i.201 f). There the Devā hold their meetings on the eighth day of each month, or when the Dhamma is taught, and also all their important festivals and gatherings (See, e.g., D.ii.268; M.ii.79; S.i.221; J.vi.97, 126; Thag.vs.1198). All Buddhas teach the Abhidhamma in the Sudhammā-hall. It is said (ThagA.ii.185) that every devaloka has a Sudhammāsabhā; this title is often used in comparisons to denote a fine hall.
