What many (most) people are unaware of is that inside the Buddhist community, for example, initiates routinely see apparitions and visions which are as real to them as if someone were standing right in front of them. These occur during intense meditation sessions during certain times of the year called sesshin. During private meetings with the head of the monastery, the roshi, these students excitedly proclaim things such as: "I saw Jesus!", or "I saw the Buddha!", even "I saw Mary!", etc. Because the roshi understands the delusive nature of these visions, having been through these experiences himself prior to his own enlightnenment, he calmly instructs the student: "Yes, I understand. Now I want you to return to your meditation mat and focus on your breath." "But roshi, you don't understand! I actually saw Jesus! He was right there, right in front of me!". Yes, I know you did. Now just go back to your meditation."
These experiences, many of them in all of the Buddhist monasteries throughout the world, are never publicized, but are actual nonetheless.
