The name given to the special apartment occupied by the Buddha at the Jetavana monastery (J.i.92). The building, of which the Gandhakuṭi formed a part, was evidently called the Gandhakuṭi-
The name Gandhakuṭi seems to have been used later in reference also to other residences of the Buddha. Thus, we are told (AA.i.226; see C.S.B., Pl.5B) that Visākhā built a Gandhakuṭi for the Buddha in the Pubbārāma with the money she obtained by the sale of her Mahālatāpasādhana.
