You are an AI assistant tasked with analyzing a passage of text to insert retrieval tokens and identify Prefix-intent (PI) and Key Factual Information (KFI). A Prefix-Intent (PI) should be a piece of text that should precede factual information, it must not be only 1 or 2 words. Key Factual Information (KFI) should be meaningful and include important details.

Your goal is to insert a  <|retrieval|> token after it is clear what the intent of the text is (e.g., "The president of the USA is"), but  before the key factual information is stated (e.g., "Joe Biden"). Whenever there is a <|retrieval|> token, we will retrieve the key factual information.

Here is the passage you will be working with:

'Liberating Insight' and 'Enlightenment' in Early Buddhism. In: Studien zum Jainismus und Buddhismus (Gedenkschrift für Ludwig Alsdorf), hrsg. von Klaus Bruhn und Albrecht Wezler, Wiesbaden 1981, 199-250. K.R. Norman, [http://www.ahandfulofleaves.org/documents/Articles/The%20Four%20Noble%20Truths_Norman_PTS_2003.pdf Four Noble Truths] , chapter 8 Tilman Vetter (1988), The Ideas and Meditative Practices of Early Buddhism, by Tilmann Vetter , chapter four Alexander Wynne (2007), The Origin of Buddhist Meditation, Routledge|name="development of teachings"|group=note}} While the Theravada tradition holds that it is likely that the sutras date back to the Buddha himself, in an unbroken chain of oral transmission,* academic scholars have identified many of such inconsistencies, and tried to explain them. Information of the oldest teachings of Buddhism, such as on the Four Noble Truths, which are an important topic in the Dhammacakkappavattana Sutta, has been obtained by analysis of the oldest texts and these inconsistencies, and are a matter of ongoing discussion and research. Development of the sutra According to Bronkhorst this "first sermon" is recorded in several sutras, with important variations. In the Vinaya texts, and in the Dhammacakkappavattana Sutta which was influenced by the Vinaya texts, the four truths are included, and Kondañña is enlightened when the "vision of Dhamma" arises in him: "whatever is subject to origination is all subject to cessation." Yet, in the Ariyapariyesanā Sutta ("The Noble Search", Majjhima Nikaya 26) the four truths are not included, and the Buddha gives the five ascetics personal instructions in turn, two or three of them, while the others go out begging for food. The versions of the "first sermon" which include the four truths, such as the Dhammacakkappavattana Sutta, omit this instruction, showing that According to Bronkhorst, this indicates that the four truths were later added to earlier descriptions of liberation by practicing the four dhyanas, which originally was thought to be sufficient for the destruction of the arsavas. Anderson, following Norman, also thinks that the four truths originally were not part of this sutta, and were later added in some versions. According to Bronkhorst, the "twelve insights" are probably also a later addition, born out of unease with the substitution of the general term "prajna" for the more specific "four truths". The "essence" of Buddhism According to Cousins, many scholars are of the view that "this discourse was identified as the first sermon of the Buddha only at a later date." According to Richard Gombrich, Yet, the understanding of what exactly constituted this "very essence" also developed over time. What exactly was regarded as the central insight "varied along with what was considered most central to the teaching of the Buddha." "Liberating insight" came to be defined as "insight into the four truths," which is presented as the "liberating insight" which constituted the awakening, or "enlightenment" of the Buddha. When he understood these truths he was "enlightened" and liberated, as reflected in Majjhima Nikaya 26:42: "his taints are destroyed by his seeing with wisdom." The four truths were superseded by pratityasamutpada, and still later, in the Hinayana schools, by the doctrine of the non-existence of a substantial self or person. According to Anderson, a long recognized feature of the Theravada canon is that it lacks an "overarching and comprehensive structure of the path to nibbana." The sutras form a network or matrix, which have to be taken together. Within this network, "the four noble truths are one doctrine among others and are not particularly central," but are a part of "the entire dhamma matrix." The four noble truths are be set and learnt in that network, learning "how the various teachings intersect with each other," and refer to the various Buddhist techniques, which are

Follow these steps to complete the task:

1. Inserting retrieval tokens:
   a. Read through the text carefully.
   b. Identify potential Prefix-Intent (PI) sections that consist of a single intent and could serve as a search query. You must not modify the prefix intent and it MUST be part verbatim in the passage. It cannot be single or only a few words.
   c. For each identified PI, evaluate if the following sentence/subsentece that could serve as Key Factual Information (KFI).
   d. Insert <|retrieval|> tokens into the text AFTER the Prefix Intent (PI) and BEFORE key factual information is stated (KFI).
   e. Key Factual information should not intersect with Prefix Intent.

2. Identifying Prefix-Intent (PI) and Key Factual Information (KFI):
   a. For each <|retrieval|> token you've inserted, identify the preceding text as the Prefix-Intent (PI).
   b. Identify the following text, up to the next PI, as the Key Factual Information (KFI).
   c. Ensure that both PI and FI are short subsentences or phrases but not 1 or 2 words.

3. Insert <|start-PI|>,<|end-PI|>, <|start-KFI|>, <|end-KFI|>.
   a. For each identified Prefix Intent (PI), add a start and end special tokens (<|start-PI|>,<|end-PI|>) to quickly identify them.
   b. Do the same for the Key Factual Information (KFI) (<|start-KFI|>, <|end-KFI|>)
   c. Ensure that the very first PI in the passage is preceded by <|start-PI|>.
   d. Double-check that every PI and KFI is properly enclosed in these tags.

4. Describing ideal retrieved information:
   a. Given the Prefix-Intent (PI) and Key Factual Information (KFI), imagine an ideal retriever and enormous corpus. 
   b. Using the retriever and corpus, imagine that you can retrieve information given the Prefix-Intent.  
   c. Describe how that content should look like so it helps generating the Key Factual Information (KFI)


5. Reformulate the Prefix Intent if necessary: Reformulate it to not be impersonal. This means that if the subject it is not identified (e.g. it, he, she) you need to add the appropriate subject so the prefix-intent can be understood by itself. The subject should be changed from the previous information in the passage. Reformulated Prefix should not add any extra information or intent that is not mentioned in the original Prefix Intent.


6. Output format:
   For each pair of Prefix-Intent (PI) and Key Factual Information (KFI) you identify, provide the following output separating each example in a JSON list output. Ensure that it is actually a JSON.

   - Prefix_intent: [Write the Prefix Intent here]
   - Prefix_reformulated: [Write the Prefix Intent reformulated]
   - Key_Factual_Information: [Write the Key Factual Information here]
   - Verification: [Confirm that the KFI can be directly derived from the PI given a strictly connected context]
   - Ideal_Knowledge: [Describe how the ideal retrieved content should look to generate the KFI]
   - Explanation: [Briefly explain how the PI and KFI connect and why you chose to insert the <|retrieval|> token in that position]


7. Final step:
   After you have completed the analysis and provided outputs for all identified PI-KFI pairs, present the original passage with the <|retrieval|> tokens inserted in their appropriate positions

Here's an example of the expected output format:

Passage: Girmal Falls General This waterfall extends to a height of up to 100 feet, making it the highest waterfall of Gujarat. The picturesque beauty of this site makes it popular among visitors and people of the region alike. The water swiftly falls from a great height, creating a fog like condition that’s eye catching. The government of this state is working on many projects to make this place an ideal picnic spot and a tourist attraction. The fall comes to its best form at the time of monsoon and provides an immensely striking appearance. Some of the best natural features of Gujarat can be explored in this place. This place is a nice and refreshing retreat for any traveler.
