I love that you asked about sharing positive energy. Positive energy moves between people the same way that negative energy does. If you surround yourself with positive people, you will benefit from that energy. It will lift you up and bless you with joy. Unfortunately, if you surround yourself with negative people, the opposite will occur, and you will need to protect yourself from the negative energy. For example: in the USA, most workers sit in small cubes for 8 hours a day while their auric fields bump up against one another in these cramped spaces. You cannot avoid sharing energy, even if you do not physically speak or touch. If the workplace is happy, the energy exchange is happy, because people bring the energy into the workplace. The same goes for events, large gatherings, homes, places of worship, etc. If more people would cleanse their energy field of negative energy and purposely seek to share positive energy as they go about their day, we would live in a kinder world.
