The tenth book of the Aṅguttara Nikāya, the Collection of the Numbered Discourses of the Buddha, collects 746 suttas or discourses whose theme is centered on groups of ten topics. The most frequent are the eight components of the eightfold path expanded to ten and also the ten components of ethics. This book is especially thick due to the continual repetitions upon repetitions with very slight variations. The volume is also notable for including extensive content on monastic discipline. As the most prominent sutta we have AN 10.26: With Kāli. Fierce criticism of the brahmanical meditation methods called "kasinas" that, in the early medieval period, were included by Buddhaghosa in his entry work to a famous Sinhalese monastery and that today some claim as "effective" methods of meditation within Buddhism. The most interesting suttas in this volume are: AN 10.6: Contemplation. Perceive without perceiving. One of the most curious things that you feel when entering the current. AN 10.14: Emotional Sterility. Doubts about the Master cause emotional sterility. AN 10.19: Abodes of the Nobles (I). When you stop looking. AN 10.29: Kosala (I). Tremendous criticism of erroneous practice. AN 10.31: With Upāli. The reasons for the establishment of the monastic code. AN 10.64: Faith. On those who have entered the stream. AN 10.65: Happiness (I). Family and friends who get together and annoy you. AN 10.76: Three things. A beautiful sutta on renunciations. AN 10.92: Hazards. Teaching about the perishable and faith. AN 10.108: Physicians: Interesting sutta on physicians and the list of known diseases that have been treated with greater or lesser success. This book does not contain false suttas. In summary, this time the arduous and exhaustive work of research and reconstruction in comparative linguistics has been especially dense and thick.
