Abhidhamma Pitaka
The Abhidhamma Pitika or its summaries are commonly chanted at Theravada funeral ceremonies. Condensed versions of the seven books of the Abhidhamma Pitaka are some of the most common texts found in Thai and Khmer manuscript collections. A survey conducted in the early 20th Century by Louis Finot found that the Abhidhamma Pitaka was the only one of the three Pitakas possessed in complete form by most Laotian monasteries. The final book of the Abhidhamma Pitaka, the Patthana, is chanted continuously for seven days and nights at an annual festival in Mandalay.
