疏「富樓那具云滿慈子」者，梵語云彌多羅尼子。滿願，是父名。父於江邊禱梵天求子，正值江滿。又夢七寶器盛滿中寶入母懷，母遂懷子，父願獲滿，從此立名。母名彌多羅尼，此云慈行。亦云四圍陀中有此品名，其母誦之，以此為名。尼者，女聲也。以母詺子，名為慈子。《增一》云「善能廣說分別義理，滿願子最第一。」

Regarding the Commentary's statement that 'Pūrṇa fully translates as Son of Compassion': the Sanskrit is Maitrāyaṇīputra. 'Fulfiller of Wishes' (Pūrṇa) was his father's name. His father prayed to Brahmā by the riverbank seeking a son, just when the river was full. Furthermore, he dreamt that a vessel of the seven treasures filled with jewels entered the mother's womb, whereupon the mother conceived the son; the father's wish was fulfilled, and he was named after this. The mother's name was Maitrāyaṇī, which translates here as 'Compassionate Practice'. It is also said that among the four Vedas there is a chapter by this name; his mother recited it, and she was named after it. The suffix -nī indicates the feminine gender. Naming the son after the mother, he was called 'Son of Compassion'. The Ekottarika[-āgama] states: 'Foremost among those who are skilled in extensively explaining and distinguishing the meanings is Maitrāyaṇīputra.'
