Note 4 — Chapter XXII · KAPILAVASTU. ITS DESOLATION. LEGENDS OF BUDDHA’S BIRTH, AND OTHER INCIDENTS IN CONNEXION WITH IT.
James Legge translation
In ‘The Life of the Buddha,’ p. 15, we read that ‘Buddha was now in the Tushita heaven, and knowing that his time was come (the time for his last rebirth in the course of which he would become Buddha), he made the necessary examinations; and having decided that Mahâ-mâyâ was the right mother, in the midnight watch he entered her womb under the appearance of an elephant.’ See M. B., pp. 140–143, and, still better, Rhys Davids’ ‘Birth Stories,’ pp. 58–63.
