Once I read in a text attributed to Hsuan Hua about how the intermediate skandha body leaves the body at time of death at specific points, or parts of the body. The place of exit then corresponding to the realm where rebirth is to take place. I don't remember the details, and I have not been able to relocate the text, but I think it said that for rebirth into hell realm the intermediate skandha body would leave through the sole of the feets, hungry ghosts I don't remember the location for, animals I think was through genitals. Rebirth into the three higher realms took place from the upper part of the body. I think it was said that rebirth into deva realm was from crown of the head, and I also think that it was said that if exit was from the heart, this was for attaining buddhahood.
Do you have this text, or know where to find it?
How does this relate to the type of phowa where the crown of the head is the exit point?
In the following quote from the commentary to the Shurangama Sutra the intermediate skandha body is equated with the eight consciousness and also with "Buddha nature", and "soul":
"When they are on the verge of dying, but when the final warmth has not left their bodies, all the good and evil they have done in that life suddenly and simultaneously manifests. "The final warmth has not left their bodies" means that the six consciousnesses and the seventh consciousness have passed out of the body, but the eighth consciousness still remains. Its passage will be marked by warmth, that is, the place on the body where the eighth consciousness leaves will be warm to the touch. For instance, if the eighth consciousness leaves through the soles of the feet, that spot will be warm. If it leaves from the legs, the legs will be warm. If it departs from the waist, the waist will be warm. If it goes out the top of the head, the top of the head will be warm. That's the "final warmth" that's mentioned here in the text. Before the eighth consciousness goes, it is referred to as the "present skandha body." Once it leaves the body it is the body between the skandhas, or "intermediate skandha body." So the text here refers to the present skandha body, before it has left the physical body. If one cultivates well, the skandha body is a Buddha. If one does not cultivate, it is a ghost. So when people ask, "Are there really ghosts?" they must first ask themselves if there are Buddhas. If they know there are Buddhas, then of course there are ghosts as well. If you are not sure that there are Buddhas or ghosts, ask yourself if there are people. If you acknowledge the fact that there are people, then you will know that there are also Buddhas and ghosts, because they are all different aspects of the same thing.
After one dies then, the eighth consciousness is called the intermediate skandha body. Before one dies it is called the present skandha body. It is also known as the "soul" and as the "Buddha nature." When a person is on the verge of death, the good and evil he or she has done is revealed and a reckoning is at hand. Depending on what one did, one will have to undergo retribution or reward. If one did good, one can get rebirth in the heavens; if one did evil, one falls into the hells. If you did more in the way of good deeds and meritorious acts, then you can leave from your head. If you did more in the way of committing crimes and creating offenses, then you'll leave from your feet. Obviously then, to leave from the upper part of one's body means one will gain a higher rebirth, whereas to leave from the lower part means one is going to fall. One's kind of rebirth is evident at death. They experience the intermingling of two habits: an abhorrence of death and an attraction to life. They are repelled and attracted when confronted with death and birth." (http://www.cttbusa.org/shurangama7/shurangama7_12.asp)
Do you agree that skandha body = intermediate skandha body = Buddha nature = soul?
Also I wonder if you have experience with dying people, have you ever noticed a warmth and/or a spot at the place where the eighth consciousness left the body?
Is the eighth consciousness a thing located somewhere inside the body?
How is all this explained in Tibetan Buddhism?
Could you refer me to any English, non-restricted, texts where such things as mentioned above is explained in detail?
