"It is on this plane that some souls are allowed to manifest
themselves to the people who are still in physical form. They are
allowed to come back . . . only if they have left some agreement
unfulfilled. On this plane intercommunication is allowed. But the
other planes. . . . This is where you're allowed to use your psychic
abilities and communicate with people in physical form. There are
many ways to do this. Some are allowed the power of sight and can
show themselves to the people still in physical form. Others have the
power of movement and are allowed to telepathically move objects.
You only go to this plane if it is useful for you to go there. If you have
left an agreement that has not been fulfilled, you may choose to go
here and communicate in some way. But that is all ... to which the agreement must be fulfilled. If your life had been abruptly ended, this
would be a reason for you to go to this plane. Many people choose to
come here because they are allowed to see those who are still in
physical form and very close to them."
