I'm feeling such a loss. Can spirituality help me get over a breakup?

Spirituality, no matter how you define it, is extremely important to getting over a breakup. It helps you look at the breakup as a blessing that places you exactly where you need to be to work on what you need to work on.
Losing that special someone triggers abandonment feelings that hearken from the deep well of primal emotions. It rips you open to the core and gives you access to your innermost self (you can finally find it because you can feel its pain).
Once open, you can bring your capacity for self-love and nurturance to this throbbing center. You can direct your yogic energy of non-judgmental self-acceptance to the source of the ache, bringing calm and peace. By WORKING WITH this painful experience rather than trying to squelch its pain, you strengthen your ability to be emotionally self-reliant and reach to your higher self.
