Chapple received his bachelor's degree in comparative literature and religious studies at the State University of New York at Stony Brook in 1976. He went on to complete his master's degree in Buddhism (1978) and PhD in history of religions (1980) at Fordham University.^[1] He noted in an interview that he initially struggled to reconcile Buddhism's "emptiness" with Yoga's self-realisation, and commented that the Yogavasistha answered the debate on "the tension between emptiness and consciousness in superbly poetic verse."^[2]

He has published numerous books and papers on the history and philosophy of Indian religions, and on the intersection of religion and ecology.^[3][4]
