When people are sick or experience an emotional upheaval, they often have a hard time staying grounded. Instead of feeling connected to the good old terra firma, they seem to be floating off somewhere. Talk to them, and they're a little flighty and unattached. Their mind wanders, making them unfocused.
How do you help someone like that? If they can walk, take them outside and sit with them near a tree. Trees are so attached to the Earth with their roots that their groundedness can have a positive affect on whoever feels a little flighty, unfocused, or unattached.
If they are too sick to go outside, buy a potted plant, something rooted in soil. Put that plant in their hospital room or bedroom where they can easily see it as they lie in bed. They may get a sense of rootedness from the plant. It could help them feel more grounded.
Talk with them about ways to feel more grounded. Have them imagine they are lying on green grass and feeling the firmness of the Earth through their bodies. Or imagine they are on a beach half buried in pleasantly warm sand. That feeling of being attached to the Earth helps people feel more connected to their own life in this present moment. It can help them heal faster and feel more enthusiastic about wanting to get well.
If they can't get outside and plants are not allowed inside, play a game with them. Each of you imagine a tree you have seen that made an impression on you. Take turns describing the tree you remember, what its bark looked like, how its roots grew into the soil, how you felt when you were near it. Whoever isn't doing the remembering should listen carefully. Just remembering the tree can help a person feel more grounded. And just being listened to can make them feel more whole.
