Silent session, followed by one question regarding the origin of people within a lucid dream. They all stem from the substrate consciousness. Even when lucid, they are not puppets on your string. As the relative dharmadhatu has no clear boundaries, it is porous so it is possible for a visitation to occur. There are accounts of people having visions of tara, padmasambhava etc. It is hard to say if these are actually tara or some figment of your imagination. But if a teaching leads to enlightenment, who else but a buddha could have taught them. The Theravada believe in metaphysical realism, the world is really out there, the self does not exist, but the world does. This is rejected by the mind only and middle way schools, there is no real world existing out there. So what was occurring on vulture's peak was pure perception. Just as you might walk right through Shambhala and not see it unless your body and mind are purified. So if the perfection of wisdom teachings are true, if teachings like the Kalachakra designed to lead to buddhahood in one life time, if they work, who else but a Buddha could have taught them.
