Hi,
Detecting long distance, is no different than having her right in front of you. Close your eyes, relax, and see her right there. 12 inches, 12 feet, 12 miles, 12,000 miles,,,all the same.
You might start by 'smiling', and giving energy to her heart. Put a healing message in there. Keep revisiting this, it is a chance for you to learn and gain confidence. Try scanning, or looking for blockages. This can be your meditation time. Calm down and relax. Intention, focus...
love,
