The Spiral Path or Lokuttara Paṭicca-samuppāda. Western Buddhist Review. 6, Dec 2012.
This article surveys the Spiral Path or Lokuttara Paṭicca-samuppāda in the Pāli Nikāyas, with some reference to Chinese parallels, exploring the similarities and differences between the presentations to further elucidate the doctrine which has been at the forefront of the teaching of Sangharakshita and the Triratna Buddhist Order. English language sources are also surveyed and critiqued. Most writing to date has focussed on a single text, the Upanisā Sutta, which is shown to be unrepresentative of the class as a whole, and a new locus classicus is suggested in the Cetanākaraṇīya Sutta. The Spiral Path is seen to conform to the general outline of the Buddhist path as consisting of ethics, meditation and wisdom.
My friend Maitiu and I are working on a study of the Chinese Spiral Path texts which can be found in section 5 of the Chinese Madhyāgama. Representatives of the main themes can be found in this block of 14 sūtras. As with other parallels the differences are relatively minor.
