There are so many "grounding" techniques, but none of them are effective if you don't "walk your talk."
One of the most pervasive specimens of "ungroundedness" going around are people who don't even realize they're not "walking the talk." Their Jekyll is talking, but Hyde is doing the walking. When a person is split like that, his soul moves out of his body－that's ungroundedness.
Not walking your talk is an out-of-body experience.
The problem of a person who does not walk his talk is weak will (weak Earth element). Source cannot use such a person for important tasks on earth because out-of-body Jekyll will say "Yes" to the challenge but Hyde will say, "I'm not enough."
