From a mythological and text critical point of view, Buddhist Studies scholar Kate Crosby argues that Prince Siddhārtha conceiving or giving birth to a son before his renunciation functions as a motif to prove that he was the best at each possible path in life: after having tried the life of a father to the fullest, he decided to leave it behind for a better alternative. In early Buddhist India, being a father and bearing a son was seen as a spiritual and religious path as well as that of renouncing one's family, and Prince Siddhārtha's bringing a son in the world before renunciation proves he was capable of both. Buddhist studies scholar John S. Strong hypothesizes that the Mūlasarvāstivāda version of the story of the prince conceiving a child on the eve of his departure was developed to prove that the Buddha was not physically disabled in some way. A disability might have raised doubts about the validity of his ordination in monastic tradition.
