釋迦譜 1.57

1.57

佛所行讚經云。甘蔗之苗裔。釋迦無勝王淨財德純備。故名曰淨飯。案淨飯遠祖乃是瞿曇之後身。以其前世居甘蔗園。故經稱甘蔗之苗裔也。

The Buddhacarita says: "Scion of Ikṣvāku, invincible king of the Śākyas, whose pure wealth and virtues were thoroughly complete, was therefore named Śuddhodana." Sengyou notes: Śuddhodana's distant ancestor was in fact the subsequent rebirth of Gautama. Because he dwelt in a sugarcane garden in a former life, the sūtras refer to him as the "scion of Ikṣvāku."
