The Great Vehicle teaches us about the appearance of Buddhas in all of the worlds in the ten directions. When a Buddha appears in a certain world, that realm is named a “pure land.” For instance, Amitayus Buddha appeared in a world far to the west of our World of Endurance. His pure land was named Highest Joy or Land of Bliss. The worlds of the ten quarters are called “the other pure lands,” since they are on other sides of our World of Endurance. A pure land is an ideal world beyond the concrete reality of our world. But if the notion of pure lands were to ignore this world of ours (the only place of reality), those places would be no more than imaginary existences. The other pure lands would have no entities unless the real World of Endurance existed (that is, unless they originated here in our minds in harmony with the mind of the Buddha). Therefore a true pure land must be realized here where we are.

This chapter opens with Sakyamuni praising the four great “hearers” who told the parable of the rich man and his poor son. By their story, they demonstrated that they understood what the Buddha had been teaching. The Buddha said:

Excellent, excellent! You spoke very well about my true merits. They are just as you said. They are innumerable, asamkhya. You could not describe them all even if you tried for many hundreds of millions of eons. I am the King of the Law. I expound all teachings expediently by my wisdom in order to lead all living beings to the stage of knowing all things. I know how far a living being can be led by a particular teaching, and what each living being has deep in his mind (in his subconscious). Nothing hinders me from knowing all this. I know all things clearly, and show my knowledge of all things to all living beings (p. 105).

Sakyamuni then told them the following simile, which is called the “Simile of Herbs” or the “Three Blades of Grass and the Two Trees.”

In Chapters One and Two, Sakyamuni firmly declared that the true teaching of the Buddha is the One Vehicle of the Lotus Sutra. He urged us to believe and accept it from the bottom of our hearts. In Chapter 4, he unveils how we can believe, accept, and understand it properly. In the previous chapters, Sariputra had been the principal direct listener to Sakyamuni’s preaching. Here his place is taken by four other important “hearers.” They are Subhuti, Maha-Katyayana, Maha-Kasyapa, and Maha-Maudgalyayana. [Maha means “great” in Sanskrit.]

The first half of the Lotus Sutra (Shakumon) expounds the teaching of the One Vehicle. The several schools of Buddhism, which are divided roughly into three types (Sravaka-Vehicle, Pratyekabuddha-Vehicle, and Bodhisattva-Vehicle), are unified in the one single teaching of the One Vehicle. Since the number three represents all the various Buddhist Teachings, “three” here implies “many” or “all.”

[The Parable of the Burning House] presents the Buddha as a concerned parent, and so brings an intimacy into the relationship between the Buddha and us ordinary people. On our part, the Buddha appears like a father to be loved and trusted in faith. On the Buddha’s part, living beings like us are his children to be saved with compassion. In all of Buddhist literature, there is no other example quite as vivid as this one in the Lotus Sutra, which presents the Buddha as the Savior of suffering humanity. Here in the Lotus Sutra the Buddha touches our hearts with a clear-cut image of his personality.

[W]e all live in a world of relativity. We cannot ignore the fact that different opinions and different understandings of the world have always existed. According to the Lotus Sutra, this diversity of opinions should be appreciated and understood as valid steps we are taking on the road to the human ideal of the ultimate truth and ultimate value. For example, we often see conflicting theories in scientific research programs. Since each theory has good reasons behind it, it may be called a truth at that particular stage. But these various hypotheses must lie within the process leading to that truth.

The teaching of the Lotus Sutra, which leads all beings without exception to Buddhahood, is the most highly exalted manifestation of the spirit of the Great Vehicle. It strives to benefit all living beings and leave behind no exceptions. This fundamental principle is clearly expounded in Chapter 2.

Although the Buddha provided the “hearers,” “private Buddhas,” and Bodhisattvas with three different ways, the essence of the three identities is Bodhisattvahood. Those who don’t realize this fact and hold on to their particular beliefs that they are either arhats (perfect ones) or “private Buddhas” (self-enlightened), are neither true arhats nor true “private Buddhas.” When he is teaching them, the Buddha regards them as being Bodhisattvas. They must be Bodhisattvas at heart even if they are “hearers” or “private Buddhas” in appearance. This is why the sutra says, “The Buddhas teach only Bodhisattvas.”

The Great Vehicle … teaches that there is only one true and perfect enlightenment, that of the Buddha. Anyone who achieves it becomes a Buddha, too. The Lotus Sutra teaches that everyone – whether they be “hearers,” “private Buddhas,” or Bodhisattvas – can attain true perfect enlightenment and become Buddhas. This perfect enlightenment of the Buddha is called anuttara-samyak-sambodhi.

A key idea of the Lotus Sutra is that the three separate vehicles of “hearers,” “private Buddhas,” and Bodhisattvas are united in One Vehicle, the Buddha Vehicle.

Besides the mythological creatures, all kinds of human and nonhuman beings assembled around the Buddha to hear his sermon. Although many of them were natural enemies, their harmonious gathering together indicates that the teaching of the Lotus Sutra applies to and unifies all beings.
