From Nara to Heian (Kyoto)
 
From Theravada to Mahayana
In the centuries following the death of the Buddha, the Sangha (Buddhist community) split into various groups and subgroups; although these different traditions generally maintained close contact with each other, the “first schism” between the Sthaviravada [Pali: Theravada] (Doctrine of the Elders) and the Mahasangika (Great Community) eventually hardened into a major division between two significantly different approaches to Buddhism....In later centuries, the term Mahayana came to denote a movement self-consciously distinct from what some of its adherents called the Hinayana, or Lesser Vehicle, their derogatory term for the mainstream that denied the authority of the Mahayana sutras and continued to adhere to the goal of arhatship. But evidence from [the first century BCE to the second century CE] shows that the authors of the early bodhisattva sutras saw the Mahayana not as a separate social or sectarian movement, but simply as one of three soteriological options [i.e. to become an arhat, a pratyekabuddha, or a Tathagata], all well within the traditional fold.

Sariputra, let us suppose that somewhere...[there was a householder who was] wealthy and enjoying life. Suppose that he had a great mansion....And suppose that this mansion had a single door....And suppose that all of a sudden the whole mansion burst forth into flames, that the householder managed himself to get out, but that he had several little boys who were still inside....So he called out to the little boys: “Come, my children, get out! The house is ablaze with a mass of flames! Do not stay there, or you will all be burned in the conflagration and come to misfortune and disaster!”
But the little boys did not pay any attention to the words of the man, though he desired only their well-being. They were not perturbed, not afraid, not frightened....Instead, they ran around playing here and there, occasionally gazing out at their father. Why? Simply because of their being foolish children.
       So then, Sariputra, the man thought: “...I should by some skillful means [upaya] cause these children to come out of the house.” Now the man knew the mental dispositions of his children and understood their interests, and he knew that there were many kinds of toys that pleased them....So he said to them: “Children, all of those toys that are pleasing to you
—for instance, little ox carts, goat carts, and deer carts—so dear and captivating; well, I have put all of them outside the gate of the house! I will give each of you whatever you need and want. Come quickly! Come out for the sake of these playthings!”

Then the little boys...quickly dashed out of the burning house at great speed....However, Sariputra, that man then gave his children...ox carts only....And, Sariputra, that man reflected: “I am very wealthy and have many treasures and storehouses; I could give other vehicles to these children, but why should I? All of these children are my children, and all of them are dear and delightful to me. I should think of all of my children as being equal and the same [and should give all of them the best vehicle].”
...By referring to these three vehicles, he attracts the beings and says to them: “...The three vehicles are yours: the disciples’ vehicle, the pratyekabuddhas’ vehicle, and the bodhisattvas’ vehicle....But then, Sariputra, just as that man...gave [his children] only one highest great vehicle, so too, Sariputra, the completely enlightened arhat, the Tathagata...does not teach an individual, personal parinirvana for each of these beings; rather, he causes all those beings to attain parinirvana by means of the great parinirvana, the Tathagata-parinirvana....” [The Experience of Buddhism, 137-9; cf. RJE, 55-60]
 
Most simply, the word bodhisattva can be defined as meaning “a being headed for Buddhahood,” that is, a being in whom the aspiration for complete enlightenment has been roused. In Mainstream [i.e. Theravada] Buddhism, the word refers primarily to the Buddha Gautama prior to his enlightenment (in all of his past lives as a bodhisattva), and to the future Buddha Maitreya, who is presently a bodhisattva, awaiting his turn for Buddhahood. In the Mahayana, however, every sentient being can be seen as ultimately “headed for Buddhahood” and so is potentially or actually on the bodhisattva path....The motivating force behind the actual practice of the bodhisattva path is the element of compassion, the desire to help alleviate the sufferings of others, either by guiding them to enlightenment or by assisting in more material ways. This factor, it is sometimes claimed, is one of the things that differentiated the bodhisattva from the arhat, and in some contexts, as we shall see, it led to the notion of bodhisattvas who reject the option of arhatship in order to continue to work in samsara for the welfare of all sentient beings.

The Huayan Sutra
Indra’s Net

The jeweled net of Sakra is also called Indra’s Net, and is made up of jewels. The jewels are shiny and reflect each other successively, their images permeating each other over and over. In a single jewel they all appear at the same time, and this can be seen in each and every jewel. There is really no coming or going.

Now if we turn to the southwest direction and pick up one of the jewels to examine it, we will see that this one jewel can immediately reflect the images of all of the other jewels. Each of the other jewels will do the same. Each jewel will simultaneously reflect the images of all the jewels in this manner, as will all of the other jewels. The images are repeated and multiplied in each other in a manner that is unbounded. Within the boundaries of a single jewel are contained the unbounded repetition and profusion of the images of all the jewels. The reflections are exceedingly clear and are completely unhindered.
 

 
If you sit in one jewel, you will at that instant be sitting repeatedly in all of the other jewels in all directions. Why is this? It is because one jewel contains all the other jewels. Since all the jewels are contained in this one jewel, you are sitting at that moment in all the jewels. The converse that all are in one follows the same line of reasoning. Through one jewel you enter all jewels without having to leave that one jewel, and in all jewels you enter one jewel without having to rise from your seat in the one jewel. [Wm. Theodore de Bary and Irene Bloom (compilers), Sources of Chinese Tradition, Second Edition, Volume 1 (New York: Columbia University Press, 1999), 473]
 
Constantly Sitting
Constantly Walking

Chih-i identifies the first of the four kinds of samadhi [the samadhi through constant sitting] with the practice known as i-hsing san-mei, rendered here as one-practice samadhi.”...As Chih-i describes it in the Mo-ho chih-kuan, one-practice samadhi is to be performed in a quiet room or a secluded and untrammeled spot. The essential requisite is that the immediate environs be free of any disturbance, human or otherwise. Only a single rope bed for meditation is to be placed in the hall; no other seats or daises should be added. The practice itself lasts for a fixed period of ninety days and may be performed alone or in a small group. Over the entire duration of this three-month period the meditator applies himself zealously to the practice of sitting motionless in the traditional lotus” meditation posture. With the exception of brief stretches of walking meditation and attending to such necessities as eating and relieving himself, he vows never to sleep, lie down, stand, wander aimlessly about, or lean against any object for support. For this reason the practice is referred to as constantly sitting.”...

Chih-i distinguishes two basic approaches to meditative practice in this one-practice samadhi: the radical approach of directly contemplating the reality of the Dharma-realm (or the Dharma-body of the Buddha) and the more expedient approach of concentrating the mind on the name, idealized image, and merits (the body of form) of a particular Buddha....
 

 
Constantly walking samadhi is identified with the practice known as...pratyutpanna samadhi, [shorthand for] the samadhi wherein one finds oneself standing face to face with all the Buddhas of the present age.”...Like the one-practice samadhi, the pratyutpanna samadhi is to be performed in isolation. The meditator selects and adorns a hall for practice, prepares all the necessary accoutrements of offering, and lays out various delicacies, fruit, incense, and flowers. Having washed himself thoroughly, he changes into a new set of robes, which is to be worn at all times in the inner sanctuary where the practice is performed. Whenever he leaves this chamber to tend to necessities, he changes once again into an older set. The practice itself lasts for a fixed period of ninety days, over the duration of which the meditator must continuously circumambulate an altar to the Buddha Amitabha. He vows never to entertain worldly thoughts or desires, never to lie down or leave the hall, and, aside from the times when he eats his meals, never arbitrarily to sit down or stop to rest until the three months are completed. [The Experience of Buddhism, 303-4]
