Here is a hilarious account of a very prominent swami who saw the Buddha, and seeing Lord Buddha's effulgence and His eyes focused on the Swami, the swami fled in fear and awe instead of staying and talking to Him!
Swami Vivekananda in his later days narrated his vision of Bhagawan Buddha in the following words:
One day, when I was sitting
I saw the extraordinary figure of a monk appear suddenly, from where I did not know, and stand before me at a little distance filling the room with a divine effulgence. He was in ochrecloth with a Kamandalu in his hand. His face bore such a calm and serene expression of inwardness born of indifference to all things that I was amazed and felt much drawn towards him. He walked forward towards me with a slow step, with his eyes steadfastly fixed on me, as if he wanted to say something. But I was seized with fear and could not keep quiet. I got up from my seat, opened the door and walked out of the room with rapid step. The next moment I thought, Why this foolish fear? I made bold and went back into the room to hear the monk, who, alas, was no longer there. I waited long in vain and felt dejected, repenting that I had been stupid enough to fly away without listening to him. I have seen many monks, but never have I found such an extraordinary expression in any other face. That face has been indelibly imprinted in my heart. It may be a hallucination, but very often it comes to my mind that I had the good fortune of seeing Lord Buddha that day.
