You can have afterlife communication through meditation. When you meditate, you relax your conscious mind. When you are relaxed, the afterlife communications can come up from your subconscious into your conscious mind.
You can learn to allow the messages to come to you by opening your mind, accepting the messages that come without trying to shape them into something and without judging whether you feel they are from your loved one. You just relax and ask your loved one to come to you, speak, or ask questions, and the first notion or message that comes to you is the response . . .
