The Purpose and Structure of Jataka Tales

The Jataka tales exist to teach moral and spiritual lessons to ordinary people through stories. Dense philosophical works were meant for monks trained in study. The Jatakas used talking animals, clever merchants, kings and hunters to explain karma, rebirth and virtue to listeners who would never sit through a formal discourse on the Abhidhamma, the tradition's systematic philosophical treatises. Each story is told as a past life of the Buddha, when he was still the Bodhisatta, the being who is working toward awakening.

The Pali Jataka is part of the Khuddaka Nikaya, the collection of minor texts within the Sutta Pitaka. It contains 547 stories. They are arranged in twenty-two groups called nipatas, ordered by the number of verses in each story. The first nipata holds stories with a single verse, and the groups grow in length until the final Mahanipata. This last group holds the ten great Jatakas, which are the longest and best loved of all.

The ten great Jatakas of the Mahanipata, with their numbers in the collection and the perfection each is traditionally taken to illustrate, are as follows.

The canonical core of each Jataka is its verses, which are called gathas. The prose stories that frame them come from the Jatakatthavannana, the Pali commentary, which is often called the Jataka Atthakatha. The commentary opens with the Nidanakatha, a biography of the Buddha that leads up to the stories. Scholars note that this pattern of fixed verses and flexible prose follows an old Indian form of storytelling in which the narrator could retell the tale each time.

The first purpose is to illustrate the path to enlightenment. Each tale shows the Bodhisatta perfecting a virtue, such as generosity, patience, wisdom or compassion, over countless lifetimes until he becomes the Buddha. The Theravada tradition gathers these virtues into ten perfections, which are giving, virtue, renunciation, wisdom, effort, patience, truthfulness, resolution, loving-kindness and equanimity. The great story of Vessantara, Jataka no. 547, in which he gives away everything he owns, is the classic example of the perfection of giving.

The second purpose is to explain the law of karma. The tales are practical case studies of cause and effect. They show that good deeds lead to happiness and harmful ones to suffering, without a word of technical doctrine.

The third purpose is to preserve ancient folklore and social memory. By taking up older Indian fables and village traditions, the tales kept local lore alive. They also give a picture of ancient Indian life, with its merchants and caravans, court intrigues, village disputes and the hard choices of hunters and farmers.

The commentary gives each Jataka a fixed frame that connects the past to the present, so that the lesson never stays locked away in ancient history. The frame has five parts, and the first, second and fifth carry most of the weight.

First comes the story of the present, called paccuppannavatthu. The Buddha is at a monastery and sees a monk or layperson facing a dilemma, such as jealousy, greed, an act of unexpected kindness or a failure of nerve. Next comes the story of the past, called atitavatthu. The Buddha says that something similar happened long ago and tells of one of his own earlier lives, often as an animal and sometimes as a king, a merchant or an ascetic.

Then come the verses, the gatha, which sum up the lesson in the canonical words. After them comes the veyyakarana, the commentary that explains the verses word by word. Last is the samodhana, the connection. The Buddha reveals who each character in the past story is now, for example that the greedy merchant of old is the deceptive monk of today and that the wise elephant was himself.

The closing identification turns a fable into a teaching addressed to the listener. The dilemma at the start is never separate from the ancient story that follows, and naming the characters at the end makes the moral impossible to hold at a comfortable distance. The same frame, repeated across the collection, gives the Jatakas their lasting shape.

The stories were loved far beyond the monastery. Sculptures at Bharhut and Sanchi, from the late second and first centuries BCE, show Jataka scenes with inscribed titles. They are among the earliest evidence for how widely the tales were known.
