Tough question, because everyone is so different. I’d say to start with self care and encourage more joy in their life to raise vibration, then explain how you feel it? If this person is unhappy, I’d start there. If they’re in a good emotional place, maybe start with the ten minutes a day challenge and asking the Archangels for Love and Light energies. Hope that helps; it’s kind of hard since I don’t know them. Finally, just spend time with them, and your energy will affect theirs in a good way, I’m sure.
