Alexander,
Jhananda has been absent from the forum for a while. I also emailed him but no response. Do you have any other ways of contacting him? I know from his post that his health was getting worse.
He is usually without internet access for periods of time. I believe he goes to the library or connects to Wifi spots as he is out in rural Arizona.
Yes, he has had health problems for several years. He was saying he was worried about his decline years ago, but then he said he made a major recovery. But, I think his physical body still causes him great suffering.
I do not know how we will deal with Jeff's mahasamadhi as he lives in isolation. Unless the Inner Director tells me when his time comes. But even if such occurs I wouldn't be able to verify it as I'm on the other side of the USA.
Living alone is difficult as one gets advanced in age: so I hope his children will be able to make sure he is physically OK.
He has created a wealth of resources for future students, and we have preserved his most important discussions. His recordings on YouTube will also be available well into the future. He is not known today, but I believe at some point in the future he will be known as one of the American saints.
Yes, it is the way of the world that with time the true dharma is lost, and authentic teachers must always re-emerge and arise to re-establish it for the spiritual good of others. We are fortunate to have had such a good teacher in our time.
