A brief introduction to the origin of the idiom "tan hua yi xian":
The Lotus Sutra, Chapter on Skillful Means

At that time, the Buddha told Shariputra: "In this assembly of mine, there are no more branches and leaves; there is only the pure and true. Shariputra, for those who are so arrogant, it is well that they withdraw. Now listen well, and I will explain it for you." Shariputra said: "Yes indeed! World-Honored One, we wish to hear it." The Buddha told Shariputra: "Such wonderful Dharma, all Buddhas and Tathagatas teach only at the right time, just as the udumbara flower blooms only once in a great while. Shariputra, you should believe what the Buddha says; his words are not false. Shariputra, the Buddhas teach the Dharma according to what is appropriate, and the meaning is hard to understand. Why is that? Because I use countless skillful means, various causes and conditions, and metaphorical expressions to expound all dharmas, and this Dharma cannot be understood by thought and discrimination. Only the Buddhas can know it."
