 Thanissaro Bhikkhu has repeatedly argued that the Pali Canon and the "Visuddhimagga" give different descriptions of the jhanas, regarding the "Visuddhimagga"-description to be incorrect.Keren Arbel has conducted extensive research on the "jhanas" and the contemporary criticisms of the commentarial interpretation.Based on this research, and her own experience as a senior meditation-teacher, she gives a reconstructed account of the original meaning of the "dhyanas".
