You surely have felt hurt by other people. When disappointment overwhelms it is helpful to sense inside your body to find where your emotional lack resides so that you can invite spiritual love in.
If you sense deeply enough, you will be able to locate a place within your body where you feel an energy drain. Most of us have one or more energetic "holes" where we try to "get" love from others.
When you discover where your energy is leaking out of your body, you can put your hand there to stop the drain. Imagine that spiritual love pouring into your auric "hole" of emotional need.
This is how you will become the most resilient in the places where you have felt the weakest in the past. When you invite spiritual love into your lack, the very places that you thought you could never give from - are the same places from which your most powerful gifts emanate.
