Thanks for the awesome resource, MD. I've been meaning to read JK for a while. After I bookmarked the page, I began reading about his life (which is pretty amazing!), and here's something interesting that I noticed. His teachings totally reflect the process by which his awakening occurred. And its same with the Buddha.
Here's the most authoritative and absolutely trustworthy description of JK's awakening (from Wikipedia

):
According to witnesses, it all started on 17 August 1922, with Krishnamurti complaining of extraordinary pain at the nape of his neck, and a hard, ball-like swelling. Over the next couple of days, the symptoms worsened, with increasing pain, extreme physical discomfort and sensitivity, total loss of appetite and occasional delirious ramblings. Then, he seemed to lapse into unconsciousness; instead he recounted that he was very much aware of his surroundings, and that while in that state he had an experience of mystical union.[59] The following day the symptoms and the experience intensified, climaxing with a sense of "immense peace".[60]
I was supremely happy, for I had seen. Nothing could ever be the same. I have drunk at the clear and pure waters and my thirst
was appeased... I have seen the Light. I have touched compassion which heals all sorrow and suffering; it is not for myself, but for
the world... Love in all its glory has intoxicated my heart; my heart can never be closed. I have drunk at the fountain of Joy and
eternal Beauty. I am God-intoxicated.[61]
Following - and apparently related to - these events,[62] in early September a strange condition, which came to be known as the process, started as an almost nightly, regular, occurrence. These new incidents continued with short intermissions until October; later, the process would resume intermittently. As in the separate three-day experience of August, the process involved varying degrees of pain, physical discomfort and sensitivity, occasionally a lapse into a "childlike" state, and sometimes an apparent fading out of consciousness explained - by Krishnamurti or those attending him - as either his body giving in to pain, or as him "going off".[63]
Basically, JK's awakening(s) happened TO him, without a teacher, almost like an accident--in a moment(s) of grace. From the small bits I have read, it seems like his teaching naturally reflected this. He was against having a teacher, and was always pointing toward each person having a spontaneous awakening.
The Buddha's awakening process was quite different. He did have a spontaneous experience of joyful absorption as a child, but that wasn't exactly his awakening. Really his awakening process began with a powerful desire to find freedom from suffering. His process from that point onwards was extremely intentional (visiting different teachers, each of whom he ultimately decided was insuffucient) and involved alot of training his mind to reach the point where there was ultimate freedom from suffering. Basically, he worked his ass off (pun intended), and once he had attained the freedom he sought (his awakening), his teachings reflected that process.
I thought that was cool to think about. Different processes, different teachings.
