A suggestion on how to study and view the Lotus Sutra

There are various teaching methods employed by the Buddha in the Lotus Sutra: simile; metaphor; parable [of which there are seven]; skillful or expedient means; logic; historical precedent; narration [current events and prior birth stories]; questions and answers; and most importantly, a direct exposition of his Enlightenment. When studying the Lotus Sutra one can reflect, "here the Buddha is speaking of his experience in a previous existence and here the Buddha is answering the question of Sariputra", etc. Are there worlds where the Buddha actually experienced parthenogenesis as the physiological method of reproducing the species or is it a metaphor or is it something else? Is the Treasure Tower a metaphor only? Bodhisattvas 500 feet tall on other worlds? Flying cars? Some things are fruitless to question or contemplate and the Buddha was silent.
