For a more substantial treatment of the path, you might like to try the lecture series by English monk Sangharakshita. Founder of the Western Buddhist Order, Sangharakshita stayed on in India after WWII to ordain as a Theravadan monk, studied Pali and Sanskrit at Benares Hindu University, and went on to practice with Vajrayana and Chan teachers. He returned in 1966 to teach in the UK, where two years later in London he gave a weekly series of eight hourly lectures on the Noble Eightfold Path that he describes as introductory for new aspirants and a revision for those already practicing. It is perhaps the most insightful explication of the subject that I've had the pleasure to encounter, one in which Buddhism is presented as a Utopian ideal encompassing every facet of human life, not just a technique for experiencing a glimpse of ultimate reality. Generally a critical reader and circumspect in praise, it comes as something of surprise even to myself to say that this series has inspired a reevaluation of my relationship to Buddhism.
Sangharakshita is a witty and linguistically limber speaker, well read and able to include examples from various Buddhist traditions, as well as from English and Christian literature. He is something of a controversial figure for teachings on family and sex relations, as well as somewhat infamous for episodes of sexual impropriety and organizational mismanagement. This lecture series was conducted when Sangharakshita was just getting started in the UK and doesn't touch on any of his later controversial teachings. If you can set aside the scandal and listen with an open mind, you'll find this series intellectually rewarding. Bodhi's book in comparison is like reading a sport's rule book – all detail but no sense of the drama of the game itself.
