Love Never Fades - it powers up Spirits who have crossed.

In a number of the events that I've been to and had the opportunity to speak with people about my book, the topic of love comes up often. Love the main emotion that powers spirits (those who have crossed into the light) to "power up" and come back to give messages or signs to those they left behind. Positive emotions help spirits who have crossed over while negative emotions (fear, anxiety, hatred) help earth-bound ghosts power up.
One instance of the power that love brings to a spirit happened when a man and his daughter came up to me earlier this year at The "Karmafest" event. As the man approached I sensed a spirit around him, a woman. He asked me about the book, and I explained that I wrote it based on my developing abilities to talk to ghosts and spirits. He asked about his wife who passed, and I instantly knew it was her around he and his daughter. His wife (who passed from an illness) immediately filled me up with so much emotion and love that she held for these two, that it caused me to visibly shake. It was overwhelming. She wanted them to know that she's around them all the time.
The man confirmed that some "odd things" happen around the house. He mentioned the strings from shades that he constantly finds wrapped in knots in the spare room (whenever he goes in there). He said that he and his wife shared a memory about knots, something from a movie they watched together. He said he couldn't understand how the knots kept happening, when neither he nor his daughter tied them, and there was no one else in the house. Obviously, it was a clear sign from his wife.
So, the love that the man and his late wife shared are giving her the power to tie those knots, and power enough as a spirit to make me visibly shake with the energy and love she has for her husband and daughter.
In short, love never fades. In fact, it powers those who have passed (and gone into the light) to send us messages they're still checking in on us from time to time, and leaving signs (if we're paying attention).
