It makes no difference how long it’s been since you’ve last had contact with someone, how far away they may be, or whether or not they have passed away. As beings, we always exist, and we are always right here, and as available and accessible as we are willing to be and have the other person be.
This is a key working principle behind the magic of the relationship resolving techniques used in my practice of therapeutic spiritual counseling, routinely yielding magical results.
