There are a few ways you can use the stone's energy. Through "elixirs", meditation, and every day use.
You an use the Bloodstone for an elixir, I link you a video:
You can atune your energies to the stone itself, and feel its energy flowing into you, and you can also carry it around in a pouch or your pocket, and have that stone influence your daily emotions/behaviors.
That's how you can use the stone's energy. I'm sure there are more ways, but these ways are more effective for me.
