Hi Lal,
I have always understood Nibbana is asankhata. Does this not also mean that it has no beginning? It does not arise at any moment?
AN3.47 explains that the charateristic of the unconditioned are opposite to the conditioned, i.e. ..”no arising is evident, no vanishing is evident, and no change while persisting is evident”. (translation bhikkhu Sujato)
I have asked another question but maybe this is lost in the thread and unseen. Can you please answer this? The question: does the concept of lifestream in essence not refer to PS?
