Most people perceive a difference between sharing a thought and giving away something, like a material possession. They believe that when you give away goods or possessions, you have "lost" them. But this is a view from a separated mind. Thought creates matter. When you share a thought, it is the same as when you give away a possession. Sharing of thoughts strengthens them. This is how Creation unfolds. So when you share, either in thought form or in "material" form, you will bring more of that back to you. Also, when you share something, you acknowledge to the Universe that you have that to give. You can only give that which you possess. This reinforcement and acknowledgment brings you more of what you have given, whether that is Love, peace, money, or possessions.
