In 1994 while I was staying in Shwe Taungong Paṇḍitārāma, Yangon, I wrote an article in answer to a question posed by a Malaysian nun, Sister Vivekanandī, who was then meditating there. It was later published in 1995 as a booklet by Buddhist Wisdom Centre, Petaling Jaya, Malaysia, entitled Cessation Experiences and the Notion of Enlightenment: Tentative Findings of a Preliminary Research.
