In the Lord's Divine mercy the interior parts of my being, those of my spirit, have been opened, and this has made it possible for me to talk to those who are in the next life, not only to those from our own planet but also to those from other planets. Therefore, because I have had the desire to know about the inhabitants of other planets and the things I have been enabled to know deserve to be recorded, let me relate those things in sections at the ends of the chapters that follow. I have not talked to actual inhabitants of those planets, only to spirits and angels who had formerly inhabited them. I have done so not just for a day or a week but for a number of months, with the help of plain teaching from heaven as to where those spirits and angels were from. The fact that there is a large number of planets with people on them and that spirits and angels come from them is very well known in the next life; for anyone who wishes is allowed to talk to them.
