These allegorical descriptions [in the Lotus Sutra] can be understood as the development of the concept of the One Vehicle. Chapter Four described how the Buddha leads all beings by faith until they reach the final stage of enlightenment. Chapter 5, The Simile of Herbs, on the other hand, tells us that living beings are now at various levels of understanding, and the Buddha patiently and compassionately expounds the law to all of them equally, although in different ways.

This simile depicts the universal quality of the Buddha, who is like a large cloud that covers all the diverse beings of this world. Chapters Two and Three have introduced the teachings of the One Vehicle (the Truth), which unifies all kinds of philosophies and religions. The One Vehicle can also be understood as a manifestation of the Buddha’s personality, because he attained the Truth and manifested it in his very body. In the “Simile of Herbs,” the personality of the Buddha, the One Thus Come (Tathagata, the title by which he described himself after his enlightenment), is symbolized by the same kind of cloud, of rain, of content, or of taste.

The Buddhist faith often expounds difficult doctrines consisting of abstract philosophical ideas. When it comes to the Lotus Sutra, however, such complicated dogmas do not appear on the surface. For this reason, some critics have argued that there are no doctrines in the Lotus Sutra. But this is not true. The Lotus Sutra does contain profound philosophical thoughts. Instead of using tortuous logic, however, the Sutra explains its philosophy in the simplified form of stories, drawing on examples familiar to us from everyday life. This is why we find many parables in the text.
