You call them spirits—your loved ones who have passed—but they are just like you, albeit living at a different level of reality. Their world is as real to them, as solid as yours. They live, they love, they play. Do not grow jealous thinking that they now love others and not you. That is human thinking. They are now in the realm of spirit, where the nature of all that is as love is clear. And so they come to know this, for they are surrounded by love, unlike in human form, where many humans do not understand their true nature.
Your loved ones may appear to you as thought, as orbs of light, wispy figures, or not at all, but they are people still … still with you when you think of them and even when you do not, only having their experiences at a different level. You will join them one day, but for now simply know that the two worlds are intertwined, and what love has joined together, no death can tear apart.
