Raises some questions:
1. Does a stream-enterer (and other ariya below arahant) "experience" nibbana, of just "glimpse" it?
2. Is nibbana an object of consciousness (as in the Abhidhamma) or is it an absence of objects?
3. Does an arahant "experience" nibbana for a short time (like jhana etc) and then return to a more-or-less normal experience (this would be the Abhidhamma view), or does he/she "remain in nibbana"?
Accounts that I've seen, such as Peter Harvey's book, The Selfless Mind, argue that a logical reading of the Suttas gives the first option for 3, and probably the second option for 2.
The 'destruction of attachment, hatred, and delusion' is also given as the definition of Arahatta, or Arahat-ness (S.IV.252=SN38.1). One might expect this to refer to the general state of the Arahat, but the way the term is used shows that it actually means the crucial transformation which makes the person and Arahat. That is, it is the state in which attachment etc. and the cankers get destroyed, so that the person now is an Arahat...
And what is the Unbinding property with fuel remaining? There is the case where a monk is an arahant whose fermentations have ended, who has reached fulfillment, finished the task, laid down the burden, attained the true goal, ended the fetter of becoming, and is released through right gnosis. His five sense faculties still remain and, owing to their being intact, he is cognizant of the agreeable & the disagreeable, and is sensitive to pleasure & pain. His ending of passion, aversion, & delusion is termed the Unbinding property with fuel remaining.
